Hongkeng Tulou Cluster, Earthen tulou cluster in Hongkeng Village, Fujian, China

The Hongkeng Tulou Cluster in Hongkeng Village, Hukeng Town, Yongding District, Longyan, Fujian, comprises Zhencheng Lou, Fuyu Lou, Kuiju Lou, Guangyu Lou, Rusheng Lou, Jingyang Lou, Qingcheng Lou, Fuxing Lou, Yucheng Lou and Qingfu Lou, built from the Qing dynasty to the present. Zhencheng Lou has two concentric rings laid out according to the bagua; Rusheng Lou is a small round building 18.2 m in diameter; Fuyu Lou is a mansion-style tulou with three internal units.

These buildings originated as residences for Hakka families starting in the 12th century and provided protection against outside threats in southeastern China. They developed over several centuries into significant settlements and remained inhabited into the 20th century.

These structures embody the daily life of Hakka communities, with private rooms arranged around a central courtyard where families gathered for shared activities. The layout demonstrates the importance of collective living within the architectural design itself.

The cluster lies in Hongkeng Village, Hukeng Town, Yongding District, Longyan, Fujian. Zhencheng Lou, Fuyu Lou and Kuiju Lou are the three buildings listed as national key cultural relics; Rusheng Lou is the smallest round building, 18.2 m across. Paths between the buildings are on foot, and interiors have narrow stairs and uneven floors, so wear sturdy shoes.

Zhencheng Lou is laid out on the bagua (eight trigrams) principle, with two concentric rings: an outer ring of earthen walls and an inner ring of rooms around the courtyard. Rusheng Lou, the smallest in the cluster, measures only 18.2 metres in diameter.
