Hapdeok Cathedral, the first parish church in Chungcheong, houses the early history of Korean Catholicism. When it was built in Sanggung-ri, Godeok-myeon, Yesan-gun in 1890, it was named Yangchon Cathedral. It was renamed Hapdeok Cathedral when it purchased the 400㎡ of land and moved to the current location in 1899. Then, in 1929, Father Perrin built a new Gothic cathedral. When the new Hapdeok Cathedral became independent in 1960, the name was changed from Hapdeok Cathedral to the Old Hapdeok Cathedral, before reverting to Hapdeok Cathedral in 1997, as it remains today.

In 1998, in recognition of its historical and architectural value, this cathedral was designated as Chungcheongnam-do Monument No. 145. Located on a low hill, it is characterized by a pair of bell towers. There are three entrances and three windows in the front of the building, the upper part of which is made of rainbow-shaped arches. The exterior walls are built from red bricks, while the window framing and the corners of the bell tower are made from gray bricks. The lower part of the windows and each side of the bell tower are decorated with diamond-shaped gray bricks. Thanks to these features, the building continues to be loved as a film location for various movies and dramas and as a great photoshoot venue for the general public.
