Wilson's observatory at Daramona, County Westmeath, Ireland, which was donated to the University of London after his death.

In 1951, UCL took over management of the Observatory from the University of London, and over the next ten years added library, lecture, and laboratory space.

In 1965, the Observatory purchased a nearby house at 33-35 Daws Lane to serve as an Annexe hosting additional office and laboratory space, including a Lunar research group led by Gilbert Fielder.

[6] The Wilson telescope was retired in 1974 (to the Merseyside Museums), and was replaced the following year with a new 24-inch Ritchey-Chrétien Cassegrain reflector which was named after the former director of the Observatory, Professor C.W.

The observatory's primary purpose is to provide UCL undergraduates with training in practical astrophysical techniques and data-handling.
