Phra Ratchawang Bowon Sathan Mongkhon

The Front Palace (RTGS: Wang Na), officially the Phra Ratchawang Bowon Sathan Mongkhon, was the residence of the royal holder of the same title (also known as the uparaja and usually translated as "viceroy" or "vice king", and sometimes as "Lord" or "Prince of the Front Palace", or "Prince-successor") during the early-to-mid Rattanakosin Kingdom. The palace was built at the same time and in the similar manner as the Grand Palace, following the accession of King Rama I and the foundation of Rattanakosin (today's Bangkok) as the capital city in 1782. It was located at the northern end of the inner fortified city, directly in front of the Grand Palace, where the king lived, and provided security to the city. Most of the Front Palace was built under Surasinghanat, who had been named by Rama I, though it saw further additions and modifications throughout the periods. It was home to five of the six Princes of the Front Palace, until the death of Wichaichan in 1885, after which the position was abolished by King Chulalongkorn in favour of a modern succession system. The palace compound was subsequently converted for various functions. Today, only the buildings of the main residence remain, housing the Bangkok National Museum. Other parts of the historical compound are now occupied by Thammasat University, the National Theatre, the Bunditpatanasilp
