Bugle Rock is a massive rock in the Basavanagudi area of South Bangalore, in the state of Karnataka. It is an abrupt rise above the ground of peninsular gneiss as the main rock formation and with an assessed age of about 3,000 million years. Bugle Rock has generated wide interest among the scientific community.
Amidst the natural rock formations, a small park with waterfalls and fountains has been developed as one of the green lungs of the garden city of Bangalore, which is frequently visited by children, families and the elderly. The park houses three temples. The densely tree-lined park developed by the Horticulture Department of the Government of Karnataka is considered a “walkers paradise” since over 750 to 1000 visitors (70% of them senior citizens) visit the park every day. One can also hear calls of a number of bats perched on the trees. An amphitheatre, which can accommodate 300 people, has been developed in the precincts of the park.
The Hindu temple Dodda Basavana Gudi or Bull Temple, said to be the biggest temple to Nandi (the bull referred to as a sacred Hindu demi-god) in the World, and a Ganesha temple are in the limits of the park. According to an inscription in the Bull Temple, a spring beneath the Nandi is the source of the Vrishabhavathi River, which flows to the west of Bangalore.
In the Bugle Rock park, in a study carried out by bat biologists, fruit bats (Pteropus giganteus) (also called Indian Flying-fox, listed as least-threatened in the 2006 IUCN Red List of Threatened Species Chiroptera Specialist Group 1996) have been recorded in roost trees, Samanea saman (rain tree), Eucalyptus sp., (Glaycindia sp.), and also in Gulmohar (Delonix regia) and jackfruit trees in the garden, tree groups and protected areas . The area is maintained by the Bangalore Development Authority (BDA). The farmland, before roost, is stated to be undisturbed and ancient.
