Like the other islands near North Berwick, Fidra is the result of volcanic activity around 335 million years ago. Fidra consists of three sections; a hill at one end with the lighthouse on it; a low lying section in the middle, effectively an isthmus; and a rocky stack at the other end.
Its name is believed to be Old Norse in origin, referring to the large number of bird feathers found there. Like the nearby Bass Rock, it has a substantial seabird population, and is now an RSPB reserve. The village of Gullane lies to the south-west, and the nature reserve of Yellowcraigs and village of Dirleton, to which parish Fidra belongs, are to the south. Remotely operated cameras on the island send live pictures to the watching visitors at the Scottish Seabird Centre in North Berwick.
Upon the island are ruins of an old chapel, or lazaretto for the sick, which was dedicated in 1165 to St. Nicholas. In the 12th century, the island formed part of the barony of Dirleton, which was granted to the Anglo-Norman John de Vaux by King David I. The de Vaux family built a stronghold, known as Tarbet Castle, on the island, but in 1220, William de Vaux gifted Fidra to the monks of Dryburgh Abbey, in the Borders. His successor built Dirleton Castle, on the mainland, as a replacement dwelling.
Robert Louis Stevenson often visited the beaches at the area known today as Yellowcraigs and it is said that he based his map of Treasure Island on the shape of Fidra. (This claim is also made about the island of Unst in Shetland.) He also mentioned Fidra in his novel Catriona. Fidra Books is a publishing house, named after the island, and which uses Fidra's outline as part of its logo. The progressive rock band Marillion also briefly mention Fidra in the song, Warm Wet Circles, which contains the line "She nervously undressed in the dancing beams of the Fidra Lighthouse", the coast nearby apparently being a well-known courting spot.
