Phra Narai Ratchaniwet
Lopburi is considered as the gateway to northern Thailand and a hub of the northern line railway. Here tourists can take the train to visit many important historic sites. Take the northern line to Lopburi station, and then choose various types of local bus to get to Phra Narai Ratchaniwet.
Phra Narai Ratchaniwet or King Narai's Palace was constructed in the Ayutthaya Kingdom before being abandoned after the death of His Majesty King Narai the Great. It was neglected until King Rama IV ordered the restoration and conversion to the present day valuable museum.
The palace can be divided into three zones: The outer royal residence comprises a banquet hall, Phra Chao Hao building, the Twelve Halls for Treasures, the royal elephant stables, and water tanks. The middle royal residence comprises, Dusit Sawan Thanya Maha Prasat Hall and Chanthon Phisan Pavilion. The inner royal residence comprises Suttha Sawan Pavilion, Phra Prathiap buildings, and the Royal Guards' residence built after King Rama IV's reign.
Close to the palace is another appealing historical spot, Phra Prang Sam Yod or The Three Crests Phra Prang. This religious site is Lopburi's chief landmark. The Khmer Bayon three crests are lined with a corridor connecting them. Due to the finding of a votive tablet imprinted with a Phra Prang Sam Yod image at the vault of main prang, Wat Rachaburana, Ayutthaya, it is assumed that originally the decorated Nak Prok Buddha image was housed inside the principal prang, the southern stupa housed an Avalokitesvara image, whilst a Prajnaparamita image was located at the northen stupa.
