Longtan Park, Park in Dongcheng District, Beijing, China

Longtan Park is a 42.3-hectare urban park in Dongcheng District, Beijing, built on the East Lake of the three Longtan lakes. Its 19.47 hectares of water are divided by bridges, pavilions and islands, with 12.99 hectares of green space and over 12,000 trees and shrubs. The park is organized around dragon-themed features such as Longtan, Longmen, Longting and Longyin Pavilion.

The site served as a quarry during the Ming Dynasty under the Jiajing Emperor, where earth and clay were extracted for brick production. These bricks were later used in constructing Beijing's city walls.

The park is built around a dragon theme: Longtan means "Pool of the Dragon", a name attributed to architect Liang Sicheng because the lake area forms the head to the tail of Longxu Gou (Dragon Whisker Ditch). Visitors can find Longmen Gate, Longyin Pavilion, a dragon-character stone forest and plants named after dragons such as dragon-claw locust. Since 1984 the park has hosted the Longtan Temple Fair, one of Beijing's main Spring Festival events.

Longtan Park lies inside the Second Ring Road in Dongcheng District, just east of the Temple of Heaven, and is reached by the park's west gate, where the Shi Chuanxiang Memorial Hall opened on 26 October 2009. The lake is divided by bridges, pavilions and causeways into islands, peninsulas and shallow banks, so a loop path links the different sections. The park also serves as a Class II emergency shelter for Dongcheng District.

The grounds are known for dragon sculptures scattered throughout, including large figures made from vegetation and flowers at different locations. These representations of dragon mythology create a visual thread that runs across the entire park.
