St Cecilia's Hall was originally commissioned by the Edinburgh Musical Society (EMS) and designed by the Scottish architect
Robert Mylne, who also designed
Blackfriars Bridge in London. The EMS was founded in 1728, and for its first 35 years its members met in the upper hall of St Mary's Chapel, a small church that formerly stood to the north of the present hall. In December 1763, after completion of Mylne's new hall, the EMS held an inaugural concert in honour of
Saint Cecilia, patron saint of musicians. St Cecilia's was the first purpose-built concert hall in Scotland when it was completed in 1763, not far behind the first in Europe, the
Holywell Music Room in
Oxford, built in 1748. Mylne designed the building with an oval concert hall on the first floor level with a rehearsal room on the ground floor. Originally, the main entrance opened out to a small courtyard off Niddry's
Wynd, and a
portico was added to the entrance around 1787. The building was later used as a
Freemasons' lodge, a warehouse, a school (headed by
Andrew Bell), and as Magdalene Cairns's Excelsior Ballroom. It was purchased by the
University of Edinburgh in 1959. ==Architecture==
