Near my accommodation in Ho-Chi-Minh City, there is one of the biggest Buddhist temple in HCMC. Still in construction the temple is very recent. The "complex" includes shops, a restaurant and houses for monks in addition to religious buildings. It is Buddhist temple so calm and relaxing with lots of serenities. The visit doesn’t exceed 1 hour even though the place is big. I really enjoyed visit those kind of temples, the architecture of Buddhist temples is quite impressive.
