The site is enclosed by a boundary wall with a monument to John Playfair, president of the Edinburgh Astronomical Institution, in the southeast corner. The oldest part is the Gothic Tower in the southwest corner, facing Princes Street and Edinburgh Castle. It is also known as Observatory House, the Old Observatory, or after its designer James Craig House. The central building with the appearance of a Greek temple is the Playfair Building, named after the building's designer William Henry Playfair. This houses the 6-inch (15 cm) refractor in its dome and the 6.4-inch (16 cm) transit telescope in its eastern wing. The largest dome of the site is the City Dome in the northeast corner. During the early 20th century this contained a 22-inch (56 cm) refractor. In 2018, the entire site was restored and new buildings were added.[1] The City Observatory site was opened freely to the public for the first time on 24 November 2018 as Collective, a centre for contemporary art.[2]

History

edit

Thomas Short's observatory

edit

In 1776 Thomas Short returned to Edinburgh, bringing with him a 12-foot (3.7 m, focal length) reflecting telescope made by his late brother James Short. He intended to open a public observatory on Calton Hill as a commercial enterprise. However, in 1736 Colin Maclaurin, professor of mathematics at the University of Edinburgh, had collected funds for a university observatory. Due to the Porteous Riots and the Jacobite rising of 1745 the funds were left unused. These were made available to build Short's observatory; and the City of Edinburgh provided a plot of land on Calton Hill. The observatory was to be open to university students.

James Craig designed the observatory, which, under Robert Adam's influence, was to look like a fortification with a wall and Gothic towers at its corners. The city controlled the building project, but the money ran out after only the first of the towers was built. Short moved into this as residence and ran the observatory until his death in 1788. An actual observatory, smaller than originally planned, was also built where the Playfair Building is now. After Short's death the observatory was kept going by his family for a while, then leased to opticians and finally abandoned around 1807. The site reverted to the city.

Short's daughter Maria Theresa Short was to return to Edinburgh in 1827. She ran a second – a popular and commercial rather than scientific – observatory elsewhere on Calton Hill. In 1850 this was removed[3] and she moved to Castle Hill, where her enterprise eventually became today's Camera Obscura on the Royal Mile.

The Royal Observatory

In 1812 the observatory was handed over to the Edinburgh Astronomical Institution, which opened its popular observatory in the Gothic Tower. In 1818 work began on the Playfair Building. Designed by William Henry Playfair this was to become the scientific observatory of the Institution. Following a loyal address to George IV in 1822 this became the Royal Observatory. Again the funds proved insufficient, so that the purchase of instruments and the employment of an observer depended on funding from the Government. After much delay the instrumentation was completed in 1831 with delivery of the transit telescope. Fraunhofer had made the lens, but after his death it fell to Repsold – and after his death to Repsold's son – to complete and install the instrument.

In 1834 Thomas Henderson took up the position of observer. This was now the post of Astronomer Royal for Scotland and Regius Professor of Astronomy in the University of Edinburgh. Until his death in 1844 he worked on Calton Hill. In 1839 he published his results regarding the distance of alpha Centauri based on observations he had made 1832/33 at the Royal Observatory, Cape of Good Hope. In 1846 Charles Piazzi Smyth became second Astronomer Royal for Scotland and set about reducing and publishing the backlog of Henderson's observations. In 1847 the Astronomical Institution – having run out of money – handed the Royal Observatory over to the Government.

 
Playfair Building and Playfair Monument in 1824

According to the English journalist William Jerdan, naturalist and oceanographer Edward Forbes, F.R.S. and his "The Red Lions", a dining club for younger members of the British Association, (named after the tavern where the first meeting was held), had occasion to run up to the observatory of Calton Hill for astronomical studies.[4]

The main purpose of the observatory was a time service. The transits of stars through the meridian were observed and used to keep the observatory clock, a sidereal clock manufactured by Robert Bryson, accurate. Accurate time was important for navigation, and mariners would bring ships' chronometers from the port of Leith up to Calton Hill for adjustment. In 1854 the time ball was installed on Nelson's Monument next to the observatory and visible from the port. This was controlled by electrical pulses from the observatory clock. A few years later the One O'Clock Gun on Edinburgh Castle was added. This was also controlled through an electrical wire, spanning the city from Calton Hill to the Castle. Today the time ball and One O' Clock Gun are tourist attractions. They are no longer controlled from a state of the art clock, but are triggered "by hand".

By 1888, when Smyth resigned, through underfunding the observatory's equipment had become largely obsolete. Also, the site had originally not been chosen through scientific investigation and its proximity to the city was causing problems. In 1896 the Royal Observatory moved to a new site on Blackford Hill. The Calton Hill Observatory, once again, reverted to the City of Edinburgh.

The City Observatory

Door to the City Observatory

In the wake of the Royal Observatory moving to Blackford Hill, a new City Observatory was created on Calton Hill toward the end of the 19th century. The 6-inch (15 cm) Cooke refractor was donated by William McEwan and installed in the dome on the Playfair Building. Additional domes were built for a 13-inch (33 cm) reflector donated by Robert Cox and for a 13-inch (33 cm) refractor transferred from the Dunecht observatory near Aberdeen. Only remnants of these two domes remain today. The City Dome was built to house a 22-inch (56 cm) refractor. This did not perform very well and was dismantled in 1926. The dome remained and was used as a lecture theatre.

The observatory opened in 1898 with William Peck as City Astronomer. Peck had previously been observer at Cox's observatory in Murrayfield .[5] After Peck's death in 1925 his assistant John McDougal Field continued to run the City Observatory.

In 1924 the Astronomical Society of Edinburgh was formed with Field as first president. Peck and Ralph Sampson, the then Astronomer Royal for Scotland, were honorary presidents. Field died in 1937; and in 1938 the observatory was leased to the Society, which ran the City Observatory until vandalism and theft of roofing material rendered the site unusable in 2009.[6]

 
Restored City Observatory, which opened as Collective, centre for contemporary art, in 2018

Collective

edit

In 2009 the Astronomical Society of Edinburgh moved out of the City Observatory and the buildings reverted to the City of Edinburgh Council.[7] The Council renovated Observatory House and the interior was restored by the Vivat Trust (a charity which aims to preserve old buildings) who let it as holiday accommodation.[8][9] However Vivat went into liquidation in 2015.[10] After being unoccupied for several years, in 2012 the Council started a programme to renovate the remaining buildings in partnership with visual arts charity Collective[11][12][13] in a scheme designed by architectural firm Collective Architecture. In 2014, Collective relocated from their gallery in Cockburn Street, Edinburgh, opened an exhibition in the City Dome[14] and received an award of £900,000 from Creative Scotland to further develop the site.[15][14] After a £4.5 million development, in 2018 Collective re-opened the City Observatory site as Collective, a contemporary art centre and restaurant. New exhibition space the Hillside shows art by artists in Scotland who have never previously shown their work in a major exhibition[16] while the restored City Dome is host to works by international artists.[11][17] William Playfair's Observatory has been restored according to his surviving plans and the original Transit instrument is now on public display. Observatory House was given a £400,000 renovation in 2021 and was offered for short term lets by Collective.[10][18]
