Quán Thánh Temple
Quán Thánh Temple is a Taoist temple near West Lake, dedicated to Huyền Thiên Trấn Vũ, guardian of the north and one of the four guardian temples of old Thăng Long. Founded in the 11th century and restored many times, its present form dates largely from 1836–1838; the main hall holds a bronze statue of Trấn Vũ cast in 1677.
