The city of Surakarta has been the capital of the sultanate since the 18th century, and the royal palaces are the biggest attraction of this place. Unfortunately, I was only allowed to visit a smaller palace called Puri Mangkunegaran, as the larger Keraton Surakarta was closed due to the visit of members of the royal family. But thanks to this, I visited Candi Sukuh, located at an altitude of 3265 meters above sea level, an amazing Hindu temple from the 15th century, reminiscent of Inca buildings.
