 Located some 50 miles ( 80 km ) south of Onor , and a few miles up the <unk> estuary ( now Varahi ) was the town of Barcelore ( now Basrur ) . Building their fortress downstream of the existing Hindu town in order to control any approaches from the sea , the Portuguese provided accommodation for some 30 casados within its walls ; another 35 casados and their families lived in a walled area at a stone 's throw . Barcelore became a busy trading centre which exported rice , local textiles , saltpetre , and iron from the interior regions and imported corals , exotic yard goods and horses .
