The Wat Pa Maha Chedio Kaew temple was built with more than a million recycled glass bottles, in Thailand’s Sisaket province, about 600 km (370 miles) northeast of Bangkok.

The amazing temple, which is also called ‘Wat Lan Kuad’ (‘Temple of Million Bottles’), features glass bottles throughout the premises of the temple, including the crematorium, surrounding shelters, even the toilets. There’s an estimated 1.5 million recycled bottles built into the temple and they are committed to recycling more, because the more bottles they get, the more buildings they are able to construct.

The construction started in 1984, when the monks used them to decorate their shelters. The shiny building material attracted more people to donate more bottles, until eventually they had enough to build the temple standing today. Bottle caps are also integrated as decorative mosaic murals. Going beyond use of glass as a sustainable building material, the bottle bricks don’t fade, let natural light into the space and are easy to maintain.
