The Ninth Century

From AD 810 to 1260, the island of Bombay was ruled by the Silhara dynasty. These kings built the original Walkeshwar temple on Malabar Hill. It was during this time that the caves at Elephanta were carved out. Although the coastal town of Kalyan was a busy port, the natural harbour of Bombay was not developed till the 17th century.
