Old Royal High School

The Old Royal High School, also known as New Parliament House, is a 19th-century neoclassical building on Calton Hill in the city of Edinburgh. The building was constructed for the use of the city's Royal High School, and gained its alternative name as a result of a proposal in the 1970s for it to house a devolved Scottish Assembly.

After the Royal High School relocated in 1968, the building became available and was refurbished to accommodate a new devolved legislature for Scotland. However, the 1979 devolution referendum failed to provide sufficient backing for a devolved assembly. Its debating chamber was later used for meetings of the Scottish Grand Committee, a House of Commons body consisting of members with Scottish constituencies. Subsequently, the building has been used by various departments of Edinburgh City Council.

With the passage of the Scotland Act 1998 and the introduction of Scottish devolution in 1999, the Old Royal High School was again mooted as a potential home for the new Scottish Parliament. Eventually, however, the Scotland Office decided to site the new legislature in a purpose-built structure opposite Holyrood Palace.

A number of uses have been suggested for the building, including a home for a Scottish National Photography Centre or a site for a Scottish Central Bank in the event of independence. In 2015, Edinburgh City Council, which currently owns the building, initiated a project to lease it to be used as a luxury hotel. However, in 2021, it was announced that the lease to the hotel developers had been cancelled, and a new use was being sought.
