The isle has obvious ecclesiastical ties, but its history predates Christianity. Multiple Neolithic graves have been found under the floor of the remains of a 12th century chapel still visible at the end of the tombolo.
In July 1958, a young schoolboy named Douglas Coutts uncovered a treasure buried under a cross-marked flooring of St Ninian’s old church. Coutts was assisting an archaeological dig on the isle when he uncovered what would turn out to be one of the greatest examples of silver and metalwork of the early Medieval period in Scotland. Nowadays, the 28 piece hoard of silver Pictish objects is on display in the National Museum of Scotland in Edinburgh.
The last people to live on the isle were the Leasks who left in 1796. Since then, the isle’s only inhabitants are local wildlife.
