Buddhist temples can be creepy. At least the Parisian ones.
If you can manage to come in at 13h on a sunday, you’ll get the monks singing some hypnotic tunes and everything. Pretty cool.
You can go in anytime, and take pics. Just leave your shoes at the door.
I’ll let you look at the pics.
Teo Chew Buddhist Temple.
Go to 44 avenue d’Ivry, Metro Tolbiac, Line 7. Then go under the building passage, you’ll get to a square. Go right and before the mechanical stairs to the left you’ll see the entrance.
