Parliament Hall, Parliament Square, Edinburgh

Parliament Hall, located in Parliament Square, Edinburgh, was built between 1631 and 1640 by Sir James Murray, with later extensions to the north by Robert Reid from 1807 to 1810. The hall connects internally to the Supreme Courts on the east, the Advocates Library on the west, and the Signet Library via a lobby to the northwest. This double-height, purpose-built hall features an impressive timber trussed roof and a basement known as the Laigh Hall, and is almost completely surrounded by later buildings. The exterior is constructed of rubble with ashlar margins, featuring an eaves cornice and a four-bay buttressed west elevation with segmental arched windows. The south wall includes a pair of ogee-roofed bartizans with wall sundials and a basket arched window.

The interior, last seen in 2014, showcases an oak trussed roof supported by stone corbels, crafted by John Scott, Master Wright to the Town of Edinburgh. The carved stone corbels, likely by Alexander Mylne from the 1630s, support the beams. The floor is inlaid with geometric patterns. The south window contains stained glass from 1866-68 by Wilhelm von Kaulbach, executed by Maximillian Ainmiller of Munich, while other windows feature heraldic glass from 1870 by James Ballantine. The east side has round arched recesses flanking the door, and there are three late 19th-century carved chimneypieces to the west by William Adams, cabinetmaker, with the central one incorporating 17th-century Italian woodwork. A timber screen is present on the south wall.

In the Laigh Hall, also seen in 2014, there is a central round-arched arcade with eight octagonal piers and simple chamfered round arches that divide the space into two areas. The ceilings are flat, with the west one ribbed.
