Bach Ma Temple... Hanoi.

Although it's not very large and can be quickly toured, it is said to be a temple of the Ly Dynasty, built in 1010 in Hanoi. Walking past the altar where incense was burned, I could enter through a large gate into the interior. There was a table set for a ritual with various kinds of sweets, and it was interesting to see many Korean snacks with Korean writing on them. Although it's not very large and there isn't much to see, it's a place worth taking a quick look around. Since it doesn't take much time, it would be nice to visit while strolling around Hoan Kiem Lake or Beer Street in Hanoi.
