The Hwaseong Fortress, located in Suwon, 30km from Seoul, is an ancient edifice built at the end of the 18th century to prevent the kingdom from its numerous enemies. It uses elements from both occidental and oriental architectures. That makes this building unique compared to any other Korean fortifications.

Today, you can visit the fortress for free, walking over the walls, from one guard tower to another and passing by the four gates of the complex. To get to the wall, you firstly must climb the hill but this worth it. You will enjoy a great view over the city and above all, you will discover walk by walk the architecture of this fortress and the different places of importance. Thiz site is for my part one of the better WHS in South Korea.
