In 1878 the King personally supervised the raising of the final central spire of the building. The throne hall was completed in 1882, on the centenary of the House of Chakri and the Grand Palace. Thus the new throne hall was given the name Chakri Throne Hall, meaning literally 'the seat of the Chakris' The northerly end of the structure is the Chakri Maha Prasat Throne Hall; all other buildings are hidden behind it. The central pavilion with its portico and roof extensions is taller and larger than the other two on the sides.
