The Yapahuwa Rock Fortress was one of the places where the Sacred Tooth Relic was kept during times of invasion from South India. The steep stair way leading to the fortress is to prevent any storming of the place by enemies. The architecture and intricacies of the the sculpture is awesome. Beyond the fortress, its possible to climb to the top of the rock. If one can make it up the steep stairs, then the rest of the climb is also possible. At the top is a remains of a chaitya and small rock pools.
