Observatory in Johannesburg is one of those rare "hidden treasure" type of suburbs in Johannesburg, located to the north east of the city and spreading across the high ridges of the Witwatersrand. It is a suburb that takes full advantage of the koppies, panoramic views and rocky terrain. Established more than 100 years ago, there are many fine old heritage houses on stands between half an acre and a full acre.
In the Footsteps of Gandhi An illustrated history of Johannesburg's Linksfield Ridge and environs by Alkis Doucakis, 2007, published by Colors, illustrated, 80 pages. This is a fascinating work of local history. It starts with the advantage of an appealing title, hanging the history of the north eastern suburbs of Johannesburg (Linksfield Ridge, Linksfield, Orange Grove, Norwood, Sydenham, and Observatory) to the association of Mahatma Gandhi and the Johannesburg German, Jewish architect Hermann Kallenbach in the early years of the 20th century.
