Bombay Castle

Bombay Castle (also Casa da Orta) is one of the oldest defensive structures built in the city of Mumbai (formerly Bombay). The current castle is a structure built by the British on the site of the Manor House built by a Portuguese nobleman Garcia de Orta. Orta had leased the island of Bombay from the King of Portugal between 1554 and 1570.

The castle was built of local blue Kurla stone and red laterite stone from the Konkan region to the south. In 1662, after the islands came under the hands of the British, the British East India Company took possession of the castle in 1665. Over the next ten years, they built a defensive structure around the manor. Around the same time, a wall was being built around a new urban centre. The wall was later demolished in 1865 after the city grew rapidly. Fragments of this wall however still exist in some areas.

Few records of the original Portuguese castle remain and historians are trying to piece together the original location of the manor. Two gates of the manor are located within INS Angre, a naval station in South Mumbai. A sundial thought to date back to the Portuguese era is also present. This sundial does not mark out the 12 hours of a day, but marks out certain periods which are deemed to be important to people of those days.

The main building within this castle is the Governor's House (Raj Bhavan) in which Gerald Aungier, the first Governor of Bombay used to stay. The residence was later moved to Parel and then to Malabar Hill over the next two centuries. The current building houses the offices of the Flag Officer Commander-in-Chief of the Western Naval Command.
