The four brick towers of Lolei, an almost exact replica of the towers of Preah Ko (although in much worse shape), were built on an islet in the centre of a large reservoir – now rice fields – by Yasovarman I, the founder of the first city at Angkor. The sandstone carvings in the niches of the temples are worth a look, and there are Sanskrit inscriptions on the doorposts.
According to one of the inscriptions, the four towers were dedicated by Yasovarman I to his mother, his father and his maternal grandparents on 12 July 893.
