Architecture and continuing use
The symmetrical U-plan front centres on a taller 1824 block and a projecting pedimented porch with Doric columns. Channelled sandstone, first-floor Ionic pilasters, balustrades and advanced wings establish a measured civic composition. Inside, the early courtroom retains notably delicate gallery ironwork.
Its story
James Gillespie Graham designed the courthouse with modifications by Robert Scott in 1824. William Spence added outer wings in 1861. Duncan McNaughton extended the building north and south in 1895 and 1898, respecting the classical language while accommodating expanding judicial work. It remains an operational court.
Why it is included
The building shows how a prominent public institution could expand over nearly a century without losing the authority of its original architectural order.
What to notice
- Doric columns framing the central arched entrance.
- Ionic pilasters and balustrades across the upper front.
- Subtle changes in masonry marking successive extensions.
Reading the surroundings
This is a working court with security procedures. Consult official access guidance, never photograph where prohibited and allow court business to take priority.
