Suwon Hwaseong Fortress, The UNESCO World Heritage
Its like "the great of wall of china" but a Korea version with an excellent view of the city of Suwon.
The fortress is large. It was told that the fortress was build during Joseon Dynasty (1392-1910) and consist of four gates face each of the cardinal directions—Janganmun (north), Paldalmun (south), Changnyongmun (east), and Hwaseomun (west)—and the seven-arch style Sumun gates straddle the point where the nearby stream reaches the palace. Above the Sumun gates is a pavilion called Hwahongmun. The fortress wall was built using Seokjae and Jeondol (bricks) and the holes between the bricks are just big enough to fire guns, arrows, or long spears through in case of an attack. The fortress was designated as Historical Monument No. 3 in January 1963, and in December 1997, it was designated a UNESCO World Cultural Heritage Site.
To go there take line 1 on the subway to Suwon Station, exit 4 and then went to the Tourism office to get the shuttle bus. Be prepared for a bit of a walk.
Personally, I feel that the palace are different compare with other palaces in Seoul. It is a palace of defense. We can watch towers on hill tops with high walls along the hills and beautiful architecture as usual.
We watched the martial art show they do most days. It was very impressive and worth going to see, and it is free to watch. I also had a chance to try the traditional archery at KRW2000 per person for 10 arrows. It was fun.
One of the best day trips ever. I highly recommend this trip for anyone that want to check out the History of Korea in this city.
