Galabedda Biso Pokuna is located 20.5 km towards Monaragala upon the Pottuvil Road.
This place is considered to be the regional palace of Princess Sugala Devi of the 12th century. The sluice gate, ponds, moats, ramparts are some of the appealing features in this historical place. The pool which is in the backyard is a fine piece of the Sinhala architecture. The pond is made out of robust rock with water inlets in opposition to the 4 facets. The water flows into the pond through the mouth of the legendary creature. It’s about 10 feet deep. An attractively carved washroom also can be seen. This is a great place for the architectural lovers.
