Karta Palace

Karta Palace (also known as, "Court of Karto", "Keraton Karta") was a palace built by Sultan Agung in Central Java in the early 1600s. 
It was located on the Oyo river, approximately due south of the current locality of Kota Gede and just west of the Plered palace built by his son, Amangkurat I.
Contemporary identification of the palace and its location, is in the terminology to identify early javanese kingdoms - the term "Mataram" as a key term -
name of a sub village at Plered territory, Plered sub district, Bantul Regency, Yogyakarta (more or less 4 kilometers south of Kotagede). Karta was a Mataram Palace complex (after Mataram Kotagede).
The structure was important logistically for Agung as he was asserting his separation from the paternal/family palace at Kota Gede, and it was located closer to the ocean coast, which was of significance in the relationship of Mataram rulers with the Nyai Loro Kidul.
Little is known about the structure from non javanese sources, as few described or pictured it. The number of non javanese visitors was limited in number. It was known to be made in entirety in timber, and was prone to being damaged by fire. 
It was destroyed by fire, and as with the remains of his son's palace compound at Plered, little or no signs of the structure remain.
