5. Blue Lagoon Chapel, Intercontinental Bora Bora Resort & Thalasso Spa, French Polynesia
Blue Lagoon Chapel in stunning French Polynesia looks like an over-water wooden thatched hut from the outside, but inside it defies belief. Inside there are green stained-glass windows, solid wood benches and altar tables, as well as a glass aisle through which you can see the emerald-green water below. The chapel is perfect for intimate weddings, and it features a large window with views of Mt Otemanu as a backdrop.
