The periphery of the fort is around 5 km. The entire fortification has two main doors one from north and the other from south. Of which the northern gate was for land connection and the southern gate was used as a passage to the sea. This route opens to the main sea through the Revdanda creek. Portuguese built a dock over here which had become non-existent over time. The north and south gate is connected directly by a long road made of stones. Now, only the western part of the compound has some relics of the ancient fort. The remaining portion has eventually become the Revdanda village with houses and patches of farmlands. Revdanda Beach is a very isolated beach and is situated near the fort. The sand is black in colour, which gives it a unique look.
