Đình làng An Hải is the communal house of An Hải village - one of the two original settlements on Lý Sơn - and serves as both a traditional village cultural center and a memorial to one of the most significant and least-known chapters in Vietnamese history. For over two centuries under the Nguyễn lords and later emperors, young men from Lý Sơn were conscripted into the Hải Đội Hoàng Sa - naval units sent each year to the Hoàng Sa (Paracel) Islands to assert sovereignty, survey sea routes, patrol the waters, and salvage shipwrecks. The crossings were dangerous and many sailors never returned.
History of the Building
According to local elders, the site began modestly in 1815, under Gia Long, as a small structure of bamboo, thatch, and local timber known as 'Sở Tam Phủ.' It was rebuilt on a larger scale in 1820 under Minh Mạng - the construction date is carved into the ridge beam inside the middle hall - in the 'chữ nhị' (二) layout of front hall and main sanctuary typical of central Vietnamese communal houses of the era.
Eight founding lineages funded the rebuilding - Nguyễn, Dương, Trương, Trần, Võ, Nguyễn Đình, Nguyễn Văn, and the wider village - though the Lê clan was later struck from the list of recognised founders after a ritual infraction, leaving seven tiền hiền (founding ancestors) honoured in the hall today. The building's current architectural character mostly dates to its 18th recorded restoration, in 1943 under Bảo Đại, with the most recent restoration in 2019 giving it the bright yellow paint common to Vietnamese coastal shrines. It was recognised as a National Historic-Cultural Relic in 1995.
The Farewell Ceremonies
Before each departure, the men held farewell ceremonies at the communal houses of An Hải and An Vĩnh - ceremonies that continue today in the form of the annual Khao Lề Thế Lính Hoàng Sa memorial, held here around the 15th day of the 3rd lunar month, in roughly the same window as An Vĩnh's own version a short distance away.
