From the Wikipedia article
Aldershot observatory is a circular red-brick building with a domed roof standing on Queens Avenue in Aldershot Military Town near Aldershot, England, home to the British Army since circa 1854. Inside is an 8-inch (203 mm) refracting telescope on a German-type equatorial mount with a clockwork drive which will run for about 2 hours without rewinding, this has a facility to vary the drive rate. The telescope and observatory building were a gift from aviation pioneer Patrick Young Alexander to the British Army, a fact which is recorded by a plaque near the observatory door. It reads: ‘Presented to the Aldershot Army Corps by Patrick Y Alexander Esq 1906’.

Background
History
In 1891, Patrick Alexander ordered the telescope from the well-known Victorian telescope makers Thomas and Howard Grubb of Dublin with all the usual fittings associated with a professional instrument of the time. It is not entirely clear where the telescope was first installed, accounts vary. It is probable that the telescope was first erected at one of Patrick Alexander's several private workshops in Bath: either 'DeMontalat Wood' or 'The Mount'. The telescope was a substantial instrument, which together with its mounting, must have weighed several tons. The telescope was fully equipped for astronomical observations and Patrick became a fellow member of the Royal Astronomical Society up…
Architecture
The building is of conventional design. It is principally of redbrick with some white stone masonry, surmounted by a cupola. There are three steps leading up to a heavy ornamental door. The dome was originally covered in a rubberoid material (modified bitumen) but in time this perished and the dome was rebuilt with copper cladding. The building today is generally in good condition. In the best traditions of Victorian engineering, the dome rotation is controlled by a pulley and rope loop, as is the dome opening mechanism. The dome opening is triangular in shape, a design which limits the usefulness of the telescope because the area of sky visible reduces sharply as the telescope is pointed…
Description
The future of the observatory is in some doubt. There are hopes that nearby streetlights might be lowered and shielded to reduce interference with observations, but in truth the instrument is little used and interest in the observatory is mainly historical. The number of soldiers based at Aldershot is being greatly reduced. The Army is expected to withdraw entirely from the area that currently surrounds the observatory and the land will be redeveloped with private housing. In its current location, the observatory will be an island in a sea of houses and some people fear that it will be targeted by vandals or, perhaps, will have to be protected with high, unsightly fences.
