It can be said to be a landmark building in the center of Belfast, with a typical Victorian classical dome, bright green roof, magnificent colonnade, intricate carvings, wide green space, and is surrounded by the most prosperous commercial street in Belfast.
The price is cheaper if you order on-site, so I suggest you don't order online. Besides, they can't scan the QR code for online orders. On-site, it's only 14 pounds for adults, but they're charging 156 pounds here, which is outrageous.
Belfast's Peace Wall is a witness to Northern Ireland's dark history. Now the whole Northern Ireland region is very peaceful and stable, and on this Peace Wall, people use cartoons to record the past history and the beautiful vision of peace. The whole wall is very long, and there are many subjects for painting, which is very beautiful. It is definitely a place you must visit when you come to Belfast.
The castle is situated in between a mountain and sea. Gardens in the surrounding are also stunning. Moreover, if you like trekking, this is an ideal location.
