There is a red brick house on the right side of Yeongsannaru Dock. It used to be the archive of the Oriental Development Company that was built in 1910 to store a wide range of documents. The Oriental Development Company was established by the Empire of Japan to implement strategic exploitation of Joseon.

According to historical records, in July 1910, the Japanese forcibly purchased 1,800 grave lots and the rivers and streams in Gungsam-myeon (Yeongsan, Seji and Wanggok) in Naju at a price of 80,000 won. At the time, the lands of Gungsam-myeon were part of the Gyeongseongung Palace, where Imperial Noble Consort Eom to King Gojong stayed. Later, in order to manage these lands, the Empire of Japan opened the Yeongsanpo Office of the Oriental Development Company at 306-13 Yeongsan-dong in front of the Yeongsanpogu Port. This is the location of the present-day Yeongsannaru tea house area. Afterwards, the lands that were bought with force were sold to Japanese migrants at giveaway prices.

Then, in the late 1920s, Mokpo, which was then a small village on the southwestern coast, began to prosper as a new town, and the office of the Oriental Development Company was relocated there. This led to the closure of the office building in Yeongsanpo. Subsequently, the building was inherited by Park Jae-cheol from his father and it has been managed by the younger Park for 20 years. He and his wife are currently running a tea house called Yeongsannaru, and the archive building, which is the only building of the Oriental Development Company that remains intact today, has been painted and renovated into a residence for the couple.
