On the morning of April 19, Kiến Thụy District held a ceremony to receive the certificate recognizing the Dương Kinh relic complex—related to the Mạc Dynasty—as a special national heritage site. Attendees included Comrade Lê Tiến Châu, Politburo member, Secretary of the Hai Phong Party Committee and head of the city's National Assembly delegation; Đỗ Mạnh Hiến, Permanent Deputy Secretary of the City Party Committee; Phạm Văn Lập, member of the City Party Standing Committee and Chairman of the City People's Council; Hoàng Đạo Cương, Deputy Minister of Culture, Sports and Tourism; other members of the City Party Standing Committee; vice chairs of the City People's Council and City People's Committee; leaders, residents of Kiến Thụy District; and numerous tourists.
The Mạc Dynasty ruled from 1527 to 1592, founded by Emperor Mạc Đăng Dung and comprising five monarchs: Mạc Đăng Dung (1527–1529), Mạc Đăng Doanh (1530–1540), Mạc Phúc Hải (1541–1546), Mạc Phúc Nguyên (1547–1561), and Mạc Mậu Hợp (1562–1592). Over 65 years, the dynasty implemented reforms and economic policies that improved living standards and social stability. Notable scholars like Nguyễn Thị Duệ and Nguyễn Bỉnh Khiêm emerged during this era.
The ancient coastal capital of Dương Kinh retains numerous historical relics, national treasures, and cultural works. The complex includes five key sites: the Mạc clan ancestral shrine (designated national relic in 2002), the memorial site of the Mạc kings (city-level historic relic, 2016), Trà Phương Pagoda (national relic, 2007), Nhân Trai Pagoda (city-level relic, 2003), and Hòa Liễu temple-pagoda (national relic, 1993). This ensemble showcases cultural, historical, and artistic values, preserving national treasures such as the Định Nam sword, statue of Emperor Mạc Thái Tổ, and bas-relief of Empress Vũ Thị Ngọc Toàn. It hosts unique intangible cultural festivals, especially the unparalleled Minh Thề oath ceremony in Vietnam.
On January 17, 2025, Deputy Prime Minister Lê Thành Long signed Decision No. 152 designating the complex as a special national heritage site—the fifth such site in Hai Phong. This recognition affirms its historical, cultural, and architectural significance and helps Kiến Thụy District and Hai Phong City promote cultural tourism, boosting economic and social development.
Mạc Đăng Dung (1483–1541), from Cổ Trai village (now Đương Thắng, Ngũ Đoan, Kiến Thụy, Hai Phong), was a seventh-generation descendant of Mạc Đĩnh Chi. Born into a fishing family, he showed exceptional intelligence and talents early on. He won the martial examination in the Lê Uy Mục era and was appointed commander in Thăng Long. In 1527, he was awarded the title An Hưng Vương and established the Mạc Dynasty with the era name Minh Đức. In 1529, he abdicated in favor of his son Mạc Đăng Doanh (Mạc Thái Tông), retired to become Retired Emperor, and chose Dương Kinh as Vietnam’s first coastal capital.
