Garhwal Himalayan forts

Garhwal Himalayas is a heavily mountainous region in Uttarakhand. It derives its name from ‘Garhs’ or forts that had been built in the region. These are medieval forts that were built in the 8^th century CE at various altitudes. These were developed as networks by ancient rulers and were used to relay information of enemy attack using smoke or fire signals. According to a recent study, these forts were built during the reign of Katyuri Dynasty between 8^th and 12^th century CE.
