Lop Buri, formerly known as " Lawo", was one of the important ancient towns of the Khmers from the10th-13th century. Many Khmer ruins are found in and around this town. During the Ayutthaya period, King Narai the Great established Lop Buri as the second capital with the help of French architects. Most of the architecture of that time reflects the mixture of Thai and Western styles. Beatiful tourist areas are Sunflower Fields which in full bloom from November to January, and various ancient palaces.
