Statement of Special Interest
'The 1894 Building' was designed and built from 1892-4 as the principal building in an outstanding and unique nationally important group of buildings within a walled compound forming the new Royal Observatory on the Blackford Hill. 'The 1894 Building' was designed with functionality to house the telescopes but is also a highly detailed bespoke design for a scientific facility which continues in the same use.
The Royal Observatory and its associated complex of buildings were built on Blackford Hill in Edinburgh from 1892-4. The complex first appears on the 2nd Edition Ordnance Survey Map of Edinburghshire (surveyed 1894, published 1897). The new observatory was built following a donation of astronomical instruments and literature to th e City of Edinburgh from the 26th Earl of Crawford from his private observatory on the family's estate at Dunecht, Aberdeenshire. Since 1822 the Edinburgh Royal
Observatory had been housed in the Observatory Building on Calton Hill however by 1888 its efficiency had been affected by inadequate buildings, outmoded instruments and by what had become an unsuitable site.
In 1888 a Royal Commission recommended that the Edinburgh Observatory should cease to be a National Scottish Institution and that its buildings should be handed over to the University. It was this threat to the future of the Observatory that prompted the
Earl of Crawford to offer his gift of the instruments and astronomical library from his own personal estate on the condition that the Government build a new building on the Blackford Hill site and maintain it to ensure a future for the Royal Observatory in Edinburgh. The publicly funded site was designed to act as a public monument to astronomy as well as a state-of-the-art research centre for the time.
The resulting brief for the architect W W Robertson (1845-1907) was to create a building to adequately house the technical instruments and library whilst also designing the group of buildings to a high level of detail and design quality befitting the buildings' status as a public monument for the city of Edinburgh. The carved stone Zodiacal designs to the main observatory building are finely detailed and the stone towers with their copper domes are both practical and highly decorative.
The multi-period site continues to be in use for the purpose for which it was built and is a nationally important for astronomical research and study in the UK and is now (2015) occupied by the Scientific Technologies Facilities Council and the University of Edinburgh. The telescopes were designed and built by Grubb Parsons of Newcastle: to the east tower is a 36 inch telescope built in 1928, which, when installed in 1930, was the largest operating telescope in Britain.
The architect Walter Wood Robertson (1845-1907) was born in Elie in Fife and studied architecture at Edinburgh College of Art. In his early career he spent time articled to the offices of both Peddie and Kinnear and Brown and Wardrop before spending some time working in London. Robertson is best remembered for his large Post Office commissions at Perth, Greenock and Dundee executed from 1897-1898, however the observatory site, completed a few years earlier, is also one of his most prominent commissions.
