Prasat Pre Rup library

On the left and right sides of the east entry tower of the second enclosure there are libraries with high towers. They sheltered carved stones with motifs of the nine planets and the seven ascetics. In the center there is a vat between two rows of sandstone pillars. Glaize suggested that this might have been, rather than a sarcophagus, a base for a wooden building or for a statue of Nandi, the sacred bull, the mount of Siva to whom the temple was dedicated.
