Coats Observatory is one of five public observatories operating in the UK, all of which are sited in Scotland.
Coats Observatory is located in Oakshaw Street West, Paisley and was designed by Glasgow architect John Honeyman, with funding coming from local thread manufacturer Thomas Coats. The observatory was operated by the Paisley Philosophical Institution, which had been founded on 8 October 1808. The design incorporated many impressive features of Victorian architecture including wrought iron work from the Saracen Foundry in Possilpark, Glasgow, carvings by John Young and stained glass windows featuring Galileo, Kepler and William Herschel.
The building opened to the public on October 1, 1883. The first telescope was a five inch refractor built by Thomas Cooke of York. Other equipment included an orrery, spectroscope and a transit telescope. Meteorological recording was undertaken on a daily basis, and has continued uninterrupted to the present day.
In 1898 an additional ten inch refracting telescope was purchased, manufactured by Howard Grubb of Dublin. This telescope is still in use at the observatory, as is the original Cooke telescope. That year also saw the addition of a pavilion to the rear of the observatory complex which housed additional astronomical and scientific apparatus and also seismic recording equipment. The pavilion went out of use circa 1930 and was demolished in 1969, but Coats Observatory continues to function as a seismic monitoring station for British Geological Survey.
Management of the observatory was transferred to Paisley District Council in 1963 and is now operated by Renfrewshire Council.
Coats Observatory is open on a daily basis (except Monday) and runs evening viewing nights throughout the winter months. Renfrewshire Astronomical Society meet there on a Friday evening throughout the year.
