granted the chapel at Corstophine to Holyrood Abbey in 1128. Before that, it was a dependent chapel of St Cuthbert's Church. By 1158, it had become a church, with altars to Saint Anne and the Holy Trinity. A burial chapel was added to the church in 1404 by Sir Adam Forrester, who died by 1405. The chapel was dedicated to John the Baptist. The chapel was erected into a collegiate church by his son Sir John Forrester. The foundation of the current church says the church was built in 1429 in the same churchyard as the earlier parish church, and was completed by 1437. The sandstone church was built with a tower and stone, octagonal spire, rectangular chancel, and a nave with transepts. This included the absorption of earlier Gothic features from the previous building and the erection of the characteristic barrel vaults, which may have concluded by 1436. The remodeling of the more sophisticated, pre-existing vault like the one in the southtransept shows a structurally slightly arbitrary pattern of two semi-quadripartite arrangement of ribs rising from a springing point at the centre of the bays. In 1548, Thomas Marjoribanks, son of Thomas Marjoribanks, burgess in Edinburgh, replaced Robert Marjoribanks upon the occasion of Robert's death, as prepend of Corstorphine Kirk and continued through the Reformation until 1567. Rev Andrew Forrester became minister in 1590. In 1634, the collegiate church was dissolved and in 1646 the building became the parish church. At that time the 12th-century church was razed and a new aisle was added to the collegiate fabric. Stones from the former church were used to built the porch. In 1828, a restoration by architect William Burn resulted in a two-storey sacristy, renovation of the nave, removal of a 17th-century aisle, and building of a new aisle and transept. The east choir and the adjacent sacristy are the only original roofs that survived and the vaults of the nave and aisle were re-made in precast concrete ribbed panels during the restoration from 1903 to 1905 by George Henderson. The church has Scottish heraldic panels and pre-Reformation relics. James Ballantine supplied the Victorian stained glass and Gordon Webster and Nathaniel Bryson supplied the 20th-century windows. Leonardo da Vinci's Last Supper was the inspiration for the heads on the carved corbels made by William Birnie Rhind. On the grounds are a war memorial, vault and gatehouse, surrounded by a boundary wall and cast iron gates. The ancient stone font, in the south transept, was brought from Gogar church in 1955.
