Gaztelugatxe.

Gaztelugatxe, a breathtaking islet off Spain's Basque coast, draws visitors with its unique geographical features and rich history. Connected to the mainland by a medieval stone bridge and a stunning 241-step zigzag staircase, the approach is an adventure in itself. Atop the rocky crag stands a charming hermitage dedicated to Saint John the Baptist, dating back to the 11th century. Over the years, it has served as both a religious site and a strategic stronghold, witnessing battles and pirate attacks, including one led by Sir Francis Drake. Surrounded by dramatic cliffs and the pristine Bay of Biscay, Gaztelugatxe also invites visitors to ring the hermitage bell for good luck. Its popularity surged after being featured as Dragonstone in "Game of Thrones," making it a must-visit for history buffs and adventure seekers alike.
