Preah Ko

For the temple, see Prasat Preah Ko (Prasat Bakong)

A short but highly acclaimed architectural period, Preah Ko is named after the Hariharalaya site of Prasat Preah Ko (Prasat Bakong) and corresponds to a brief time-frame between the Kulen-style of Jayavarman II and the Bakheng period of Yasovarman I. Most sites dating to this period are ascribed to the reign of Indravarman I although many temples were certainly initiated before his reign and several were subsequently completed by Yasovarman I.

Temples continued to be constructed out of brick with extensive stucco-work and sandstone colonettes and lintels but several major architectural innovations date to this reign. Single platforms housed multiple - 3, 5 or 6 - towers and 'libraries' and entrance gopuras make an appearance as do, increasingly, concentric, moated enclosures. In decoration terms, dvarapalas and devatas - either in stucco or inserted sandstone blocks - become common features and elaborate, intricate reliefs appear on heraldic-style lintels.
