The first lighthouse of Mangaluru is located in the heart of the Mangaluru city. This "Light House" was built by Hyder Ali, the de facto ruler of Mysore. It stood as the watch tower of Sultanate of Mysore Navy under him and his son Tipu Sultan. The huge watchtower on the hill served as a base for the British, from where many resident commanders of the British Navy would monitor the movement of travelling ships. The base of the light house has a library, with a reading room named after Karnad Sadashiv Rao, a renowned freedom fighter.
