Built in the seventeenth century, the Surakarta Hadiningrat Royal Palace was once the nucleus of the Javanese Kingdom. It has a number of vintage sculptures, ancient battle equipment and is home to the Sanggabuwana Tower, which is steeped in history too. Certain parts of the premises are closed to the public, such as the King's residency, but there is still plenty to see for a visitor. Other than that, the palace regularly hosts a number of religious and cultural events in the city.
