Siem Reap and the West Baray Lake
The man made lake was formed in in the 11th c., and was 8km long by 2.2km wide and 7m deep (about 22 feet). Later a temple was built in the centre of the lake.
YOu can also see a golfcourse in the foreground... I think siem reap has 5 or 6 professional courses to cater to all the tourists that come to visit.
