The causeway looking south towards Gopura III is 152 metres in length
The causeway you see above connects Gopura IV with the 3rd Gopura, is 152 metres in length and should have 35 pairs of boundary stones, but practically all are missing. Where are they? Its a mystery. To the left of the causeway is another small rectangular pond, where army families camped nearby take their water. As you approach Gopura III, you'll see that its the largest and widest part of Preah Vihear temple, with long lateral halls on both flanks. Inside the gopura, the lintels and pediments are amongst the temple's best preserved and well worth seeking out in the various nooks and crannies.
