The ancient site at Dholavira, is flanked by two storm water channels; the Mansar in the north, and the Manhar in the south.
Reservoirs are cut through stones vertically. They are about 7 meter deep and 79 meter long.
The site was occupied from about 2900 BC for about a millennium, declining slowly after about 2100 BC, briefly abandoned and then reoccupied, finally by villagers among its ruins, until about 1450.
A sign board with ten huge Indus signs found on the floor of a room at the North Gate was probably originally displayed above the gateway.
