At the top of the green hill, visitors will find the remains of Nimrud Castle, which means Nimrud, the steep land, and gave it this name because it rises nearly 800 meters above sea level, and is surrounded by deep valleys, and therefore it provides majestic panoramic views of the surrounding lands of the Golan. The castle dates back to the thirteenth century, when it was built specifically in the year 1275, with the aim of guarding the road to reach Damascus against the armies coming from the west. Therefore, it is surrounded by high walls and has watchtowers, and it is wonderfully preserved compared to some other historical monuments from that period, so it is considered one of the most beautiful ancient castles in the area.
