The Front Palace (Thai: วังหน้า, RTGS: Wang Na), officially the Phraratchawang Bowon Sathanmongkhon (พระราชวังบวรสถานมงคล), 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 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.
