St. Joseph Cathedral
Stepping inside neo-Gothic St Joseph Cathedral (inaugurated in 1886) is like being instantly transported to medieval Europe. The cathedral is noteworthy for its square towers, elaborate altar and stained-glass windows. The first Catholic mission in Hanoi was founded in 1679.
The main gate to St Joseph Cathedral is open daily from 5 to 7 am and 5 to 7 pm, when Masses are held. Guests are welcome at other times of the day, but must enter the cathedral via the compound of the Diocese of Hanoi, the entrance to which is a block away at 40 Pho Nha Chung. After walking through the gate, go straight and then turn right. When you reach the side door to the cathedral, ring the small bell high up to the right hand side of the door to call the priest to let you in.
