Phimai Historical Park is in the middle of Phimai town, some 63 kms from Nakhon Ratchasima (also known as Korat). The centre-piece is Prasit Hin Phimai, the Khmer temple that is orientated towards Angkor and formerly linked by Khmer empire highways. Constructed in Khmer Hindu style during the 11th-12th centuries, it served the local populace who had been Buddhist since the 7th century. The main building stone is red sandstone, which has been sculpted into large blocks. The interior walls tend to be of laterite. Since the site was opened in 1989, following restoration that began in the 1960s, it has become increasingly popular. Expect buses decanting crowds, both tourists and locals, especially at weekends. You will have to be patient with your camera to get folk-free shots!
