The heart of the palace is formed by the Gothic cloisters, decorated with ceramic tiles. Near the cloisters stands the large clock tower. To the south of this tower is a large gate, known as the Triton Gate, flanked by two domed towers. The gate is profusely decorated in Manueline style and shows a malicious looking triton on top of a large sea shell supporting a bay window. There are several other gates in the palace, all in a different style, from oriental to medieval. Near the Triton Gate are the main residences of the palace, including a ballroom with a large chandelier. Also worth mentioning is the magnificent Arabic room, with an intricately decorated ceiling.
