Stone upon stone, held together without mortar, and yet they have lasted for over 500 years. The Thimlich Ohinga dry-stone walls make up the most important archaeological site in East Africa.

European architecture mixed with Indian design: That is the trademark of this district in Mumbai. The Victorian buildings date from the 19th century; the Art Deco ensemble from the 20th century.
