Historically the forest was called Orijangnim (오리장림) but nowadays it is also widely known as the Jacheon Forest (자천숲). The name Orijangnim originates from the fact that in olden days, before roads were established, there was a thick forest that stretched as far as "O-ri (five-ri or 1963m)"surrounding Jacheon-ri. As the national road was developed, the forest was divided into two parts, and afterwards major parts of the forest were lost to school buildings, wider roads and Typhoon Sara. It’s surely a pity that only the remaining settlements near Jacheon village can give us a feeling on what life was like in the forest long ago. However, as you drive down the un-crowded road, surely you will be able to feel the tranquility of the region. Around 400 years ago when the forest was first created, villagers annually held a ritual at midnight on the 15th of January of the lunar year to pay tribute to their ancestors and wish for peace and safety in the village. The forest houses more than 10 species of trees that come in a variety of fantastic shapes looking just like potted plants. In the summer, the cool wind of Gohyeoncheon Stream, flows in front of Jacheon Village and keeps visitors cool and refreshed, while shade from the trees of Orijangnim seem to completely blot out the the sun.
