The Astronomical Observatories of Jai Singh c12.2

c12.2

50. The observatory is situated to the south-west of the present city, in the quarter called Jaisingpura, on the north bank of the river Sipra. From the Water Works it is half a mile west. The general situation is seen in the attached map, and in figure 60. The river bank is corroding away, and about a quarter of a mile to the east of the observatory is seen the remains of a well, now standing in the river itself. The observatory is 125 feet north from the river, and is hardly in danger owing to this proximity; but the drainage about the observatory is not under control. There is a small, and, apparently, fresh nullah quite close by, and the foundations of the Digaṁśa Yantra have already been partly worn away.
