Tron Church, High Street, Edinburgh

Tron Church, located on High Street in Edinburgh, was built between 1637 and 1647 by John Mylne and John Scott, with later alterations made by John Baxter in 1785, R and R Dickson in 1828, and Robert Rowand Anderson in 1888-1889. This church features a distinctive square plan in a Dutch-influenced Classical-Gothic style, highlighted by an octagonal steeple that crowns a prominent clock tower. It is constructed from pale ashlar stone and adorned with ornate moulded dressings and obelisk finials.

The northern entrance elevation consists of three bays, showcasing pedimented and traceried round-arched windows. Fluted Ionic pilasters are present, with the lower parts panelled and topped with obelisk pinnacles. The advanced central section features a round-arched timber door, complemented by a cartouche and a key-stoned circular window above, along with an open pediment displaying the Town Arms. Large timber double-leaf doors are located on either side. The tall, three-stage clock tower and steeple begin with a squared lower stage that has channelled pilasters and a traceried window on each face. Above the parapet, there are scrolled clock faces with octagonal corner piers connected by round-arched flying buttresses to a tall octagonal stage, which culminates in a smaller octagon with round openings, leading up to a stone spire. The east and west elevations are gabled and feature a 'naïve-and-aisles' treatment, with a moulded string course and large round-arched windows flanked by smaller ones, topped with shallow pediments and obelisk finials.

Inside, the church boasts a fine hammerbeam roof using a sexfoil pattern. The interior has been largely stripped out, revealing the foundations of the 16th century Marlins Wynd beneath ground level, which is accessible via a timber viewing platform and walkway. The church also features leaded stained-glass windows, grey Scottish slate, and cast-iron rainwater goods with ornamental rainheads.
