Sejong National Arboretum

The 65-hectare arboretum in Sejong, about 120 kilometers south of Seoul, features 1.72 million plants from 2,834 species in 20 various thematic exhibition gardens, where visitors can get a glimpse into Korea’s traditional and modern garden culture.

There's a Korean traditional garden which features a replica of the backyard of Changdeokgung, arguably the most beautiful palace garden in Korea.

Unique features of this arboretum includes the “aquatic plant garden walk” which is a 2.4-kilometer waterway from the recharge area of Geumgang River that circles the arboretum. It presents a variety of different scenes by season and time.

Changgyeonggung Green House

Built in 1909, Changgyeonggung Green House is the country’s first western style greenhouse. Located inside of Changgyeong Palace in Jongno-gu, the greenhouse was designated as national cultural property in 2004 in recognition of its historical value and architectural significance.

In front of the building, a small maze garden and a renaissance style fountain are situated.

The greenhouse is a 10.5-meter-high steel structure with glass windows and roofs covered with plate glass.

Currently, the greenhouse is used as a space for exhibiting natural monuments and wildflowers. There are also native plants of Ulleungdo and Dokdo, such as Dongbaek flower, Camellia japonica.

Because of its relatively small size, the greenhouse doesn’t feel grand or fancy, but it has its own classy and elegant vibe.

The greenhouse holds a dark history surrounding its foundation. The Japanese demolished the temples in Changgyeonggung to open a zoo and the botanical garden during their occupation. Their ulterior motive was to degrade the authority of the Joseon-era palace.
