Lambay Island is a small island on the east coast of Ireland situated two miles off the coast of North County Dublin and approximately six miles north of Howth. This secluded anchorage is off the island's drying boat harbour located on the island's western and mainland facing side.

Lambay Island is a small island on the east coast of Ireland situated two miles off the coast of North County Dublin and approximately six miles north of Howth. This secluded anchorage is off the island's drying boat harbour located on the island's western and mainland facing side.

Although sheltered to the east by the island it only makes for an exposed anchorage. A swell wraps around the island making it uncomfortable in all but very settled conditions and the tide runs very fast between the island and the coast causing unsettled lumpy waters. It is best suited for a lunchtime stop in settled conditions and would not make for a restful overnight stay. With the exception of a single easily avoided rock, unmarked and covered, access to the boat harbour is unimpeded and the approach is straightforward.
Please note

The pier and island are privately owned and no landing should take place. Visitors must stay aboard and cannot come alongside without prior permission. In most southerly conditions a better option is Saltpan Bay situated close to the northwestern corner of Lambay Island.

What's the story here?
Lambay Island's Harbour and principal buildings on the western side
Image: mj drones External link

Lambay Island is the largest island off the east coast of Ireland. Covering and area of about 2.5 km2 (0.97 sq mi) it rises 126 m to its highest point that is a hill known as Knockbane. The island's high ground lies to the east with steep cliffs standing along the northern, eastern, and southern coasts of the island. By contrast the western side has low-lying land and gentle slopes. As a consequence, it is upon the western side that almost all of the island's buildings stand, the Castle, the coastguard cottages, guest residences, and the Catholic chapel, all of which are fronted by the harbour.

The harbour is made up two arms that dry at low water to sand. There is a sandy beach by the harbour. It offers a tolerable anchorage in easterly conditions. However, the harbour and island are private so no landing should take place here unless prior consent has been obtained.

The anchoring area offshore is subject to a heavy run in and particularly so during easterly gales and an only be considered a fair-weather temporary stop.

Positioned 2 miles offshore and nearly in front of the Rogerstown Inlet. Lambay Island is the most conspicuous feature of this coastline. Its east point, called the Nose of Lambay, is elevated 55 metres above high water, and the 123 metres high Knockbawn is its highest summit. The west side of the island is low, rocky and shallow close to the shore with some outlying dangers that need to be observed off its corners. The rest of the island is made up of high bold cliffs where at least 5 metres of water can be found 200-metres off the southern shoreline and 10 metres of water off the northern and eastern shorelines.

The channel between Lambay Island and the mainland is wide and straightforward for leisure craft with all the dangers on Lambay Island’s western side. It is quite safe for leisure vessels to give the mainland shore a sensible berth and take care to avoid the rocks on the island side. The least depth in the channel between Lambay Island and the mainland is 9.7 metres except for Burge Bar, with a least depth of 7.6 metres. It is a straightforward channel for leisure craft to approach the west side of the island.

This said, if passing Portrane Point, the southern arm of the Rogerstown Inlet, standoff at least 500 metres to avoid the visible Cable Rock.

Situated 2 miles offshore Lambay has ample depths all round. It is situated just within the 20-metre contour, and on an extension of the Bennet Bank ridge with depths of 14.6 to 16.5 metres on it. Two sandbanks, however, extend north and south from the island. Frazer Bank, made up of sand, with 7 to 9 metres of water over it extends up to a mile to the north and likewise Hoskyn Bank to the south. Although deep these banks should be avoided in strong easterlies. Tidal streams attain 2.5 knots in Lambay Sound.

Northern Approach Vessels approaching from the north should pass a ½ mile outside the Skerries Island Group that consists of three islets; Colt, St. Patrick’s and Shenick Islands. It is possible to cut through the sounds of the island group but this requires some involved navigation. Details are available in the Navigating through the Skerries Islands Route location route. As a rule, newcomers are better off staying well outside of the Skerries Group.

North Eastern Approach Vessels rounding in from the north and northeast should pass outside of the Tailor’s Rocks north cardinal buoy situated off Scotch Point, at the Islands northwestern tip. The buoy marks Taylor Rocks a patch that extends 300 metres north by northwest of Scotch Point.

South Eastern Approach Vessels rounding in from the south and southeast should pass should outside Burren Rocks. This is a reef, visible at low water, that extends about 400 metres off of the western extremity of Lambay and dry to 0.6m. These are marked by a lighted starboard hand beacon that stands upon the rocky head. The ledge, however, extends a further 30 metres out from the beacon so give it a sensible distance.

Initial fix location From the initial fix approach the pier that will be readily evident on the shoreline, on a bearing of due east. Be careful not to be pushed northward by a flood tide as an unmarked submerged rock with 1.2 metres of water over it is situated about 200 metres out from the shoreline and 200 metres north of the pier. Vessels approaching along the northwest corner of the island may avoid this by keeping at least 300 metres offshore as they progress around the island.

Haven location Anchor about 100 metres out from the mouth of the harbour in shale that provides very good holding. This is a private harbour and island so no landing should take place here unless prior consent has been obtained.

Why visit here?
Lambay Island derives its name from the Viking word 'lamboy', meaning 'lamb' and 'øy', or 'ey', meaning island, so 'Lamb island'. This most likely originated from the ancient practice of sending ewes to the predator-free island for the summer grazing and returning them to the mainland in autumn.

The island's ancient Irish name was 'Reachra' means 'place of many shipwrecks'. Indeed the mirroring mainland coastal area 'Portrane' is derived from Port Reachrainn taking its name from the island. This ancient name is aptly depicted in the sad events surrounding the RMS Tayleur outlined in the Seal Hole Bay anchorage entry on the island's eastern side.

Although the island has a Nordic name the history of human inhabitation of the island goes way back before the Vikings came here. Lambay has been peopled from perhaps as early the Mesolithic period 7,000 BC to the present day. Lambay was important in the Irish Neolithic period as a ground stone axe quarrying and production site from about 5,000 BC to 500 BC. Two outcrops of porphyritic andesite, or Lambay porphyry as it is more commonly known, were utilised and they manufactured flint tools here that are believed to be of such high quality that they were of an ornamental standard. The quarry site is also unusual in that it is the only British Isles Neolithic stone axe quarry with evidence of all stages of production, from quarrying to final polishing.

Other findings of ancient inhabitation include a 20th-century survey uncovering the remains of an enclosure to the south of the present church. It suggested a connected moated site with diverse connected graves. A further number of Iron Age burials were discovered in 1927 during repair works to the island's harbour. First-to second-century A.D. objects were also recovered from island burial sites. They included some Roman-like metal brooches or fibula, a beaded necklace known then as a torc, bronze discs, and many other objects. There is no evidence today that the Romans made it to the Irish mainland, but it is believed that the island was probably populated by a mixture of Irish, Romano-British, Gallo-Roman, and others, that most likely would have included a few Romans as well. It is strongly believed that a small group of British refugees from Brigantia, fleeing the Roman conquest in A.D. 71-74 came here. The island was known in Roman times, as the Greeks Pliny and Ptolomeo were certainly aware of the island and charted it as Limnios.

St. Colmcille is said to have established a monastic settlement on Lambay circa 530 AD, and Ireland's Viking period began with the first-ever raid on the settlement in 795. In 1467, it was provided by statute that the Earl of Worcester, then Lord Deputy, be granted Lambay to build a fortress for England's protection against the Spaniards, French and Scots. Worcester paid the Archbishop of Dublin 40 shillings per annum, and though he had a licence to build a castle on Lambay, it is not certain that it was built. After the 1691 Battle of Aughrim, the decisive battle of the Williamite War in Ireland, the castle was used as a concentration camp for the defeated Jacobite troops. More than one thousand were imprisoned there; some died of wounds and starvation. They were eventually released in the bounds of an oath of allegiance for fear they would join a foreign army and England would have to fight them again.

The island's west-facing harbour was constructed in the 1820s by the famous engineer Alexander Nimmo. By the standards of the time, it was much larger than required for such a small island, and its construction serves to highlight the strategic importance of its surrounding sea area for shipping bound for the capital. In 1805, the leasehold of Lambay was inherited by Sir William Wolseley, and in 1814 it was acquired by the Talbot family of Malahide. In 1860 the existing farmers were removed and replaced with English and Scottish tenants. Having sold nearby Portrane House, Count James Considine bought Lambay in 1888, developing the island for hunting.

Cecil Baring, 3rd Lord Revelstoke (1867-1934)

In turn, the Baring family bought Lambay Island in 1904 for £9,000. Originally the Barings were a German Protestant family who became heavily involved in banking. They founded the Barings Bank that received recent notoriety when it was brought down by the rogue financial trader Nick Leeson. Cecil Baring had been working at the New York branch of the family banking business in the latter years of the 19th century, and he developed a great interest in natural history and travelled extensively in pursuit of this interest. At home, he also developed a great interest in the wife of one of his co-directors, Maude Louise Lorillard whom he fell entirely in love with. She divorced her husband and married Baring and eighteen months after his marriage Cecil saw an advertisement in 'The Field' titled 'Island for Sale'. He immediately bought Lambay Island to escape to with his beautiful wife.

Once the sale was complete Baring hired Sir Edwin Lutyens, one of the greatest architects of the time, to work on renovation the small late 16th-century fort with battlemented gables and 15th-century blockhouse. The castle was subsequently turned into a fine mansion that was so deftly executed that only a trained eye can tell the new from the old. He was retained many years later to work on other buildings such as the 1930s White House, situated close to the harbour, a largely single-storey horse-shoe shaped house with high roofs and white walls, built for the couple’s daughters Daphne and Calypso and their families.

In total the estate includes domestic extensions to the old castle, a village of cottages, a communal hall, two-family houses, a harbour and boathouse and a distinctive open-air real tennis court, the only one remaining in Ireland, plus a chapel located on an isolated promontory. Cecil Baring became Lord Revelstoke in 1929 and died in 1934. He passed on the castle and island to his only son Rupert Baring. Rupert worked for two years with Baring Brothers in Liverpool and New York, where he socialized with Irving Berlin and Rodgers and Hammerstein. He wrote lyrics and verse, including a project of Aesop's Fables which was admired by his friend, Sir John Betjeman. Another close friend, filmmaker Michael Powell, wrote the screenplay for the film Black Narcissus while staying with Revelstoke at Lambay. Under his sixty-year stewardship of the Island, Lord Revelstoke's established "a sanctuary for seabirds, an enclosed ecology, and largely unspoilt even while the capital has grown northwards, with housing and light industry spreading up into the country opposite Lambay. "

Today Lambay is owned by Lord Revelstoke's family trust, and Alexander Rupert Baring, the Seventh Baron Revelstoke, who is currently in occupation. The family island contains some fine structures and gardens, furniture and fittings that are all laid out in the arts and crafts-style popular in his great-grandfather's time. They have remained more or less untouched for eight decades. Close to the house is the last surviving substantial elm tree forest in Ireland.

It also supports one of the largest and most important seabird colonies in Ireland, with over 50,000 Common Guillemots, 5,000 Kittiwakes, 3,500 Razorbills, 2,500 pairs of Herring Gulls, as well as smaller numbers of Puffins, Manx Shearwaters, Fulmars and other species. Along the shores, Lambay has the largest concentration of grey seals on the east coast, and there are several caves in the cliffs much frequented for giving birth to their pups. Ashore, a herd of about 200 fallow deer were introduced to the island and, oddly, wallabies. It appears Dublin Zoo became overcrowded in the 1980s and some of their numbers were placed on the island. The colony is now four or more strong and may usually be seen at or near the summit, fenced off from the cattle.

Sadly, the island is privately owned and the family value their privacy, and also the welfare of the nesting wild bird population and unusual animals, so no landings should take place. However, Alex Baring recently sought planning permission to upgrade the island's infrastructure, including its sewage and electricity systems, and to make alterations to some of the islands numerous residences in preparation to put the island on a commercial footing, so this may not always be the case.

What facilities are available?
There are no facilities on the island and no landing should take place. The island is privately owned by the Revelstoke family and the owners value their privacy.

Any security concerns?
Never an issue known to have occurred anchored off this private offshore island. Vessels are most likely to be alone or in the company of other anchored yachtsmen.
