Singapore
From wikipedia: The Changi Museum is a museum dedicated to Singapore's history during world war 2. I feel really bad that I can't remember much about the place... I remember something about prisoners of war building the chapel, but not much more. Good thing there's wikipedia to the rescue!
Here's the chapel replica.
Some more blurb from the museum. We saw some paintings there too. The place was pretty tranquil, so it's very fitting as the site for the chapel replica, I think.
