A
祠堂 is a clan ancestral hall, where a lineage keeps its spirit tablets, holds weddings/funerals, and gathers for Qingming and other festivals. Especially prominent in Guangdong, Fujian and Jiangxi, where an entire village may share a single surname and a single
祠堂. Compare
寺 (Buddhist temple) and
庙 (temple to deities/heroes).
