Hongneung Arboretum (Hanja: 洪陵樹木園) in 57 Hoegi Avenue/Hoegi-ro, Cheongnyangni 2-dong 207-beonji, Seoul Dongdaemun-gu is the first generation arboretum of Korea. It was established in 1922 when experiment forests were built on Hongneung burial model, which is the former imperial tomb of Empress Myeongseong of Yeoheung Min Clan - an empress who assassinated by Japanese Agents at Okhoru Pavilion, Gyeongbok Palace, Seoul Jongno-gu in 1895.
On the 780 square meters area southwest of Mt. Cheonjang, there are 9 gardens such as a garden of conifers, a garden of broadleaf trees and an ornamental garden, 3 botanical gardens with edible & medicinal plants garden, an aquatic garden and a wetland garden. There are 6 resting places as well.
Hongneung Arboretum has beautiful scenery for every season. The garden of broadleaf trees behind the main building is the one that shows the change of season most dramatically. The hundreds of broadleaf trees appear in their best in autumn. It is good for nature education walks in the arboretum because of good explanations on nameplates of species and characteristics of trees. There are also many things to see at the Forest Science Exhibition Hall which provides visitors with knowledge and information of the value of forests, forestry, and the forest industry. The building itself is an exhibition because the hall is made of Korean wood. Inside, there are three general exhibition rooms, a regular exhibit hall, a planning exhibit hall, and a special exhibit hall.
You may look around from Garden 1 to Garden 9 in regular order or take the course from Garden 2, pass the Forest Science Exhibition Hall to the mountain ridge ending at Garden 1. Note that it takes approximately 3 hours whichever course you may take.
