George Heriot's School is a Scottish private primary and secondary day school on Lauriston Place in the Old Town of Edinburgh, Scotland. In the early 21st century, it has more than 1600 pupils, 155 teaching staff, and 80 non-teaching staff. It was established in 1628 as George Heriot's Hospital, by bequest of the royal goldsmith George Heriot, and opened in 1659. It is governed by George Heriot's Trust, a Scottish charity. Architecture The main building of the school is notable for its renaissance architecture, the work of William Wallace, until his death in 1631. He was succeeded as master mason by William Aytoun, who was succeeded in turn by John Mylne. In 1676, Sir William Bruce drew up plans for the completion of Heriot's Hospital. His design, for the central tower of the north façade, was eventually executed in 1693. The school is a turreted building surrounding a large quadrangle, and built out of sandstone. The foundation stone is inscribed with the date 1628. The intricate decoration above each window is unique (with one paired exception - those on the ground floor either side of the now redundant central turret on the west side of the building). A statue of the founder can be found in a niche on the north side of the quadrangle. The main building was the first large building to be constructed outside the Edinburgh city walls. It is located next to Greyfriars Kirk, built in 1620, in open grounds overlooked by Edinburgh Castle directly to the north. Parts of the seventeenth-century city wall (the Telfer Wall) serve as the walls of the school grounds. When built, the building's front facade faced north with access from the Grassmarket by way of Heriot Bridge. It was originally the only facade fronted in fine ashlar stone, the others being harled rubble. "George Heriot's magnificent pile" became known locally, and by the boys who attended it, as the "Wark". In 1833 the three rubble facades were refaced in Craigleith ashlar stone. This was done because the other facades had become more visible when a new entrance was installed on Lauriston Place. The refacing work was handled by Alexander Black, then Superintendent of Works for the school. He later designed the first Heriot's free schools around the city. The south gatehouse onto Lauriston Place is by William Henry Playfair and dates from 1829. The chapel interior (1837) is by James
