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. Peniscola was a filming location in HBO's Game of Thrones in Season 6. The town appears as Meereen, in Slaver's Bay on the continent of Essos.
