St James's Palace is the most senior royal palace in the United Kingdom. Located in the City of Westminster, although no longer the principal residence of the monarch, it is the ceremonial meeting place of the Accession Council and the London residence of several minor members of the royal family. Mainly built between 1531 and 1536 in red-brick, the palace's architecture is primarily Tudor in style. A fire in 1809 destroyed parts of the structure, including the monarch's private apartments, which were never replaced. Some 17th-century interiors survive, but most were remodelled in the 19th century.
