Lopburi - Fortifications

Fort Tha Po in the north-west, and Fort Chai Chana Songkhram and Pratu Chai in the south still remain from the massive fortifications that surrounded Lopburi. French engineers also built dams and sluice-gates in the north of the town for a large reservoir. King Narai built a pleasure palace, the Phra Thinang Yen Kraiso Sahavarat Pavilion, or the Yen Pavilion for short, on an island in the lake, now filled in. With imagination it is still possible to get some idea from the ruins of how beautiful it must have been.
