Balgay (Gaelic: Baile (na) Gaoithe) is a suburb in the west end of Dundee, Scotland. The name, derived from Gaelic, seems to mean 'stead of the marsh/wind' . During the 17th century, Balgay House was built and now this has become incorporated into Royal Victoria Hospital. Balgay Hill and Victoria Park were acquired by Dundee City Corporation in 1870 as public parks. The Mills Observatory designed by James MacLellan Brown was added in 1935 at the summit of the 143m hill. It is the only full-time public observatory in UK.
