Harvard's first astronomical observatory was established in 1839 in Cambridge, Massachusetts and became the Harvard College Observatory. Boyden Station was established to allow for observations from the Southern Hemisphere and was originally located in Arequipa, Peru. The Station was moved to a spot near Bloemfontien in the Orange Free State, South Africa in 1927. Harvard stopped direct support of the site around 1966.
