Visitors to Hanoi’s historic Imperial Citadel of Thang Long can now explore the UNESCO World Heritage Site with a new Korean-Vietnamese guide, created by the Seoul Metropolitan Government using its official city fonts and colors. The Seoul Metropolitan Government said Thursday that it will distribute the Korean-Vietnamese guide to mark Hangeul Day on Friday and deepen cultural exchanges with Hanoi. The project comes as Seoul and Hanoi mark 30 years of their friendship-city relationship, adding a cultural dimension to ties between the two cities. The guide covers nine major historic sites and nine key artifacts, with a numbered map designed to help visitors follow a clear route through the citadel. Among the sites highlighted are Hanoi Flag Tower, Doan Mon Gate and an underground bunker, while artifacts in the permanent exhibition are arranged chronologically to illustrate the site’s history. The Imperial Citadel of Thang Long, built during Vietnam’s Ly dynasty in the 11th century, is one of Hanoi’s major historical and cultural sites and is listed as a UNESCO World Heritage site. S
