Aberlady (Scots: Aiberleddy, Gaelic: Obar Lìobhaite) is a coastal village in the Scottish council area of East Lothian.
Etymologically, Aberlady seems to be a Cumbric place-name meaning something like 'bushy river mouth' (cognate with Welsh aber 'river mouth' and llusog 'bushy'). During the Northumbrian settlement of the Lothians, the Angles founded a religious settlement at Aberlady which they probably called Pefferham.
In the Middle Ages, Aberlady was an important harbour for fishing, sealing, and whaling and was designated "Port of Haddington" by a 1633 Act of Parliament. However, its origins are much earlier.
Aberlady had strong links with the monasteries at Iona and Lindisfarne from the 7th century, and its role was to facilitate the pilgrim traffic between the two sites. Previous archaeological excavations have shown traces of a Culdee chapel, and Pope Gregory X made reference to the church which he called "Aberlefdi". The 8th century Aberlady Cross fragment can be seen at the National Museum of Scotland in Edinburgh. A reconstruction of this finely carved cross was erected in 2011 by Aberlady Conservation & History Society.
Aberlady Parish Church dates back to the 15th century. It was re-built in 1887. In 1986, the parishes of Aberlady and Gullane were merged, and the Manse is now in Gullane.
The "Aberlady Heritage Project" is a community-led project, and in 2008 it surveyed three sites - the medieval harbour quay commissioned in 1535, the Iron Age fort and associated souterrain at Kilspindie, and the Anglo-Saxon site at the Glebe. Aberlady boasts the largest collection of stray Anglo-Saxon finds yet discovered in Scotland.
In 1952, Aberlady Bay became the UK's first Local Nature Reserve or LNR. Amongst its other conservation designations are: Site of Special Scientific Interest or SSSI; Special Protection Area or SPA; and Ramsar site. East Lothian Council provides Reserve Wardens.
Waterston House, overlooking Aberlady Bay, is the headquarters of the Scottish Ornithologists' Club (SOC). It is named after George Waterston, the founder of the Royal Society for the Protection of Birds.
The Library holds over 3,500 items and is said to be the largest ornithological library in Scotland.
The art gallery space is named after wildlife artist Donald Watson who was President of SOC. The gallery specialises in bird-related paintings, but in May 2008 it had a textile exhibition named "Flights of Fancy".
The author Nigel Tranter was inspired to write on his daily walks on the nature reserve. A cairn in his memory stands at the car park by the wooden footbridge; Nigel Tranter referred to it as "the bridge to enchantment".
Aberlady Conservation & History Society is the local focus for conservation in the built and natural environment of the village and its surroundings.
Aberlady is close to several well-known golf courses including Luffness, Kilspindie and Craigielaw.
Aberlady Bay, between Aberlady and Gullane, holds the wrecks of eight 19th or early 20th century fishing vessels, which have been designated as maritime scheduled ancient monuments, and two wrecks of XT-craft, training versions of the X-class submarine.
