Trinity College Kirk

Trinity College Kirk was a royal collegiate church in Edinburgh, Scotland. The kirk and its adjacent almshouse, Trinity Hospital, were founded in 1460 by Mary of Guelders in memory of her husband, King James II who had been killed at the siege of Roxburgh Castle that year. Queen Mary was interred in the church, until her coffin was moved to Holyrood Abbey in 1848.

The original church design was never completed. Only the apse, choir (with aisles) and transepts were completed.

The church was located in the valley between the Old Town and Calton Hill, but was systematically dismantled in 1848 due to the construction of Waverley Station on its site. Although its stones were numbered in anticipation of rebuilding and were stored in a yard on Calton Hill, by 1872, when a replacement church was built on the newly formed Jeffrey Street, only a third were left which were used to construct a version of the choir and apse which was the hall of the new church.
