It has an earlier rotating roof designed by John Smeaton who also designed the Eddystone Lighthouse. The Observatory housed what was for many years the largest refracting telescope in the world, designed and built by Thomas Cook of York, whose firm also built the Greenwich transit instrument. It was restored and refitted to mark the British Associations 150th Anniversary meeting in York in 1981 and was officially opened by its President H.R.H. the Duke of Kent, G.C.M.G., G.C.V.O.
