Kalapa Court, the palace of the king, stands on a platform of pearl in the centre. The building is nine stories high. The roof and floor of the king’s chamber consist of crystal plants that radiate heat for warmth. The city is shaped like a square, and surrounded by walls made of ruby. There are four gates for entry made of precious stones. There are 31 pavilions each of which is surrounded by gardens and streams.[1]
