In this video, contributor Skysurfer brings us some amazing aerial views of castles and castle towns in the Spanish region of Valencia. The first town shown is that of Peniscola, a small coastal town in the province of Castellon. The town's castle dates to the 12th century and possibly well before. Its profile has risen in recent years since it appeared as a filming location in HBO's hit Game of Thrones TV series. In Season 6 of the series, the town appears as Meereen in Slaver's Bay, on the continent of Essos.
