Coates Hall was originally designed by
David Bryce for Sheriff Napier in 1850 as a small Baronial house. In 1891 the building was bought by the
Scottish Episcopal Church for use as the
Edinburgh Theological College and enlarged by Sydney Mitchell adding a late gothic chapel. In 1913
Robert Lorimer added a storey to the main block. In 1995 Coates Hall was sold to St Mary's Music School and houses the (de-consecrated) chapel which is used for concerts. The chapel contains three stained glass windows. by
Ninian Comper which includes Scotland's first saints,
St Columba and
St Ninian. The school also has two libraries, staff offices, bedrooms for boarding pupils, and 25 music practice rooms. Academic subjects are mainly taught in two 20th century buildings within the school grounds. The school is surrounded by gardens in the heart of Edinburgh's
West End and has excellent transport connections due to its proximity to
Haymarket railway station and connecting bus and tram links. The Song School within the nearby Cathedral precinct is still used by the choristers for daily practice, where they are surrounded by murals by
Phoebe Anna Traquair. It was these murals (1888–1892) which won Traquair national recognition. Within a tunnelled ceiling interior the east wall depicts the cathedral clergy and choir. The south depicts Traquair's admired contemporaries such as
Dante Gabriel Rossetti,
William Holman Hunt, and
George Frederic Watts; the north, birds and choristers sing together. The west shows the four beasts singing the
Sanctus.
Royal High School In 2016 the school put forward a fully funded £25 million proposal to move its location to the
old Royal High School in Edinburgh in competition with another proposal to convert the site to a hotel. The school's plans were accepted by the Edinburgh Council planning committee in 2016 and would have allowed the school to increase the number of its students. Two hotel plans were rejected by the Edinburgh Council planning committee in 2015 and 2017. The St Mary's Music School obtained a 125-year lease from Edinburgh Council for £1.5 million so that plans could go ahead after the Council cancelled their agreement with Duddingston House Properties in January 2021. ==Notable alumni==
