Post Office is located just next to Notre Dame Cathedral, so that you can easily imagine the life of French Colonial Time once you see that. This Post Office was built between 1886 to 1891. Once you step inside the building, you would feel total French Architect such as looping arches,telephone boxes, and cannot imagine that it is inside Vietnam. Including the cathedral, the strong French colonial relics still remain there. By the way, please try to buy cute postcard and send it to your family/friends, will be nice memory for your trip.
