St. Fillan's parish church is situated at the end of a narrow path next to Aberdour Castle in Fife. Dating from c.1140, it was consecrated in 1178, and is of mixed Norman and Second Pointed Gothic in style, with a south aisle and porch added in the 15th C. and a further extensions in the 16th C. It was abandoned as the parish church in 1790, when the Countess of Morton decided she did not like the people of Aberdour coming to worship so close to her home, Aberdour House. A new church was built on the High Street. Having fallen into ruin, St. Fillan's was restored 1925-6, with Angus stone slabs forming a new roof.
The church is surrounded by a kirkyard that includes the grave of the Rev. Robert Blair (1583 - 1666), who was chaplain to King Charles I (1600-49). Nearby is St. Fillan's Well, also known as the Pilgrim's Well, which was once known for its eye-healing properties.
