St Cecilia's Hall is a small concert hall and museum in the city of Edinburgh, Scotland, in the United Kingdom. It is on the corner of Niddry Street and the Cowgate, about 168 metres (551 ft) south of the Royal Mile. The hall dates from 1763 and was the first purpose-built concert hall in Scotland. It is a Category A listed building.

Robert Mylne was a Scottish architect and civil engineer, particularly remembered for his design for Blackfriars Bridge in London. Born and raised in Edinburgh, he travelled to Europe as a young man, studying architecture in Rome under Piranesi. In 1758, he became the first Briton to win the triennial architecture competition at the Accademia di San Luca. This made his name known in London, and won him the rivalry of fellow Scot Robert Adam.
