Can you guess what material was used to create the green sections of the ceiling? I bet you can’t. This ceiling is made of… 1.6 million beetles! Jewel Beetles to be exact. This incredible ceiling art is Heaven Of Delight and can be found at the Royal Palace in Brussels. Heaven of Delight was made by Flemish artist Jan Fabre, a man renowned for working with strange media including blood, sperm and all manner of insects. It took 30 people and four months to glue all the bugs together.
