Located on a high hill with a height of 112 meters in Palma, proudly stands a beautiful round-shaped structure – Bellver Castle. Its construction began in 1300 by order of the King of Mallorca. Circular fortresses are rarely found in Europe – the prototype of Bellver Castle was the ancient Herodion fortress in Israel, which had the shape of a circle with four towers.
