Ta'ndulva'di Fort, about ten miles south-east of Mahim and three north-east of Safale station on the Baroda railway, stands on a hill about 1900 feet high, at the south end of the Mahim range. It is notable to the east of the railway between the Virar and Safale stations. On the hill-top are several rock-cut cisterns and signs of large rough fortifications. At the foot of the hill, on the east, flows the Vaitarna, which is tidal nine miles further to Manor. Near the river, also at the foot of the hill, is Lalthan village with a reservoir said to have been built by the Portuguese. [Mr. W. B. Mulock, C.S. Mr. W. B. Mulock, C.S.]
