The Astronomical Observatories of Jai Singh c10.12

c10.12

The lower part of the structure is now, more or less permanently it seems, below the water level of the locality. The height of the water varies³ but for a great part of the year it covers the lower part of the quadrants and the steps and prevents access to the west quadrant altogether; and it makes the structure useless for astronomical purposes. If the instrument is to be saved, means must be taken to prevent the water percolating to the foundations.
