maintained by the World Monuments Fund. It has continued the cautious approach to restoration, believing that to go further would involve too much guesswork, and prefers to respect the ruined nature of the temple. One of its former employees has said, "We're basically running a glorified maintenance program. We're not prepared to falsify history". It has therefore limited itself primarily to stabilisation work on the fourth eastern gopura, the House of Fire and the Hall of Dancers.
The outer wall of Preah Khan is of laterite, and bears 72 garudas holding nagas, at 50 m intervals. Surrounded by a moat, it measures 800 by 700 m and encloses an area of 56 hectares (140 acres). To the east of Preah Khan is a landing stage on the edge of the Jayatataka baray, now dry, which measured 3.5 by 0.9 km (2 by 1 mi). This also allowed access to the temple of NeakPean in the centre of the baray. As usual Preah Khan is oriented toward the east, so this was the main entrance, but there are others at each of the cardinal points. Each entrance has a causeway over the moat with nāga-carrying devas and asuras similar to those at Angkor Thom; Glaize considered this an indication that the city element of Preah Khan was more significant than those of Ta Prohm or BanteayKdei.
Halfway along the path leading to the third enclosure, on the north side, is a House of Fire (or Dharmasala) similar to Ta Prohm's. The remainder of the fourth enclosure, now forested, was originally occupied by the city; as this was built of perishable materials it has not survived. The third enclosure wall is 200 by 175 metres (660 by 574 ft). In front of the third gopura is a cruciform terrace. The gopura itself is on a large scale, with three towers in the centre and two flanking pavilions. Between the southern two towers were two celebrated silk-cotton trees, of which Glaize wrote, "resting on the vault itself of the gallery, [they] frame its openings and brace the stones in substitute for pillars
