In Lampang Thailand, we came across this old lens, it is a hole in a door.
It seems that the "lens" has been there for many, many years.
In the small and dark room behind the door (forbidden for women), they've put up a blanket.
On the blanket you can see the (inverted) image of the Wat (temple) outside.
A long time ago, this was considered some sort of a miracle.
