A temple in the Grand Palace, built by Rama I in 1789, and renovated several times later, eventually becoming one of the most beautiful buildings in the Grand Palace complex. The four-story roof of the palace is covered with red and green tiles and a gilded pagoda. The doors and windows are painted in gold and black paint, making the building more magnificent. The palace was originally intended for the coronation and the reception of important guests, but since his remains were displayed here after the death of Rama I, they were later used for funerals, where the remains of the king and members of the royal nobility were placed before their cremation.
