Located immediately behind Thai Hoa Palace, on either side of a courtyard, these halls were used by mandarins as offices and to prepare for court ceremonies. The hall on the right showcases intriguing old photographs (including boy-king Vua Duya Tan’s coronation), gilded Buddha statues and assorted imperial curios. Behind the courtyard are the ruins of the Can Chanh Palace, where two wonderful long galleries, painted in gleaming scarlet lacquer, have been reconstructed.
