The building most characteristic of the ruins of Palenque is the great palace with its distinctive square tower with stone ceiling, an interior column and a spiral staircase. Experts agree that it was from here that Maya royalty and priests watched the sun set behind the Temple of Inscriptions, located diagonally opposite. This happened every December 22 or every winter solstice. There were many rooms inside the palace for the house of the ruler, his family and their relatives. It's a large building of 85 meters from north to south and 60 meters from east to west, so more than 5,000 square meters.
