Đình Vũ East Entrance North Side Lighthouse

A 12-meter tall white cylindrical metal tower stands 11 meters above sea level on the north side of the Đình Vũ branch entrance. This structure, featuring a pyramidal base, guides vessels toward the inner harbor of Hải Phòng, approximately 1.1 km away. Its light emits an isophase white or red signal every three seconds, with a geographic range of 10.7 nautical miles. The lighthouse is accessible only by boat, situated where the river channel begins.

Why it matters: This light is essential for maritime traffic navigating the Đình Vũ branch of the Red River, directly supporting the shipping lanes that serve the inner harbor of Hải Phòng. Its directional light, shifting between white and red, provides critical guidance for vessels entering and exiting the port, helping them avoid potential hazards in the river mouth.
