Just down the small alley to your right is the entrance to Đình Ngọc Hà, the village hall of the old village of Ngọc Hà. Originally located west of the Thăng Long Imperial Citadel, Ngọc Hà was gradually absorbed as Hanoi grew. It was part of the Thập Tam Trại, thirteen villages established under the Lý dynasty to cultivate the land near the capital, and it was especially known as a horticultural village, growing flowers for the imperial court. The community hall sits on a small island surrounded by water and has been restored several times, including in the late 19th century and after damage during the Indochina War. As you enter, notice the tall pillars, kneeling stone elephants, and a screen wall carved with a tiger — traditional symbols intended to protect the site. The building follows a classic layout, with a large ceremonial hall richly decorated in carved and gilded wood, while the sanctuary at the back is the most sacred part of the complex. The đình is dedicated to Huyền Thiên Hắc Đế, the village’s protective deity, historically associated with defending the kingdom under the Lý kings. If it’s open when you visit, it’s worth taking a quick detour inside.
