Hon Gai Church (Hong Gai Church) is located on Dao Hill, Halong City, where you can capture the panorama view of Halong City center and look over to Bai Tho Mountain. The church was built first in 1933 basing on Roman architecture, but was destroyed in 1972 during Vietnam War. In 1998, the reconstruction made the church look much more spacious and decent with 42 meters in length, 11 meters in width, and a 33 meters bell tower. It is the first in Halong Bay and biggest church in Quang Ninh until now.
