Trinity College Church of Edinburgh was founded in 1460 by Mary of Gueldres, widow of King James II, who had been killed at the siege of Roxburgh Castle on August 3 of that year. Since construction was incomplete when Mary died in 1463, her funeral was held at Brechin Cathedral, but she was buried in the collegiate church. Work on the church was discontinued in 1531, at which time only the choirs and transepts were complete. Still, Thomas Rickman, architect and architectural antiquary, once remarked that the interior of Trinity College Church was "a very beautiful, decorated composition with the capitals of the piers enriched with foliage, not exceeded in design or execution in any English cathedral." After the Reformation, the Crown transferred the church to the Edinburgh magistrates who held it for 300 years, when it was purchased by the North British Railway Company for the construction of Waverly Station. In May 1848, before demolition, the Society of Antiquaries of Scotland undertook a search to locate the unmarked burial site of the queen so that her remains could be transferred to the royal vault at Holyrood Chapel. A female skeleton of the approximate age of the queen was discovered in the chantry chapel in front of the site of the altar, a place of honor which helped form the opinion that these were the remains of the queen. However, a few months after the removal to Holyrood was complete, the discovery in the center of the apse of a second female skeleton of similar age created a stir regarding which of the two was the queen. The second skeleton was also transferred to Holyrood Chapel but was entombed outside the royal vault. To this day, it is not known which of the two is the queen. The church was located on the west side of Leith Wynd at the base of Calton Hill and is clearly detailed, along with the associated Hospital, on the 1647 map of Edinburgh drawn by James Gordon of Rothiemay.
