Seoul Sajikdan Front Gate leads to various areas related to Seoul Sajikdan (Altar) and the park. The gate was constructed in 1395. During the Joseon dynasty, it would have been positioned in the north. This was thought to be the direction of the gods.
In the late 18th century, the gate was moved to the east after being damaged by a typhoon. In 1962, it was moved to its current location to make room for a new road. It is now located about 14 meters (45 feet) behind its original location.
The design features a pyeongsammun construction with three doors in a row. The roof design is known as matbae, which makes it look like its being covered with a book.
The pillars that hold up the roof deviate from regular shapes. This is important in illustrating architectural styles in Korea and the changes they have undergone over the years.
