Sri Maha Mariamman temple on Bangkok's Silom Road
Just up and across the street from Silom Village is one of the few purely Hindu temples in Bangkok. Built in the late 1860s by Tamil immigrants, the colorful temple now hosts the faithful of many nationalities.
Visitors are welcome to the temple, but you must take off your shoes and no photography is allowed inside the temple. Even taking pictures from outside can sometimes get you a mean look from one of the attending priests.
