A Nhà thờ họ (chữ Nôm: 茹𠄜户, lit. 'lineage hall or clan ancestral house') or từ đường (chữ Hán: 祠堂) is a Vietnamese traditional place of worship of a clan or its branches which established by male descendants of paternal line. This type of worship place is most commonly seen in northern Vietnam as well as middle Vietnam. An ancestral death anniversary will be held yearly at nhà thờ họ and this anniversary is usually used as an occasion to renew the relationship between clan members.
