A brand new hotel has opened in Madrid’s city center made entirely of waste, according to the Agence France Presse. The walls of the Beach Garbage Hotel, the brainchild of German artist Ha Schult, is made of materials found in landfills, the beaches and even flea markets. The five-room hotel, located in Plaza de Callao, was constructed to coincide with the annual International Tourism Fair held in Madrid.

The five-room hotel contains roughly 12 tons of garbage, including fishing nets, plastic bags, skateboards, clothing, old tires, and even a mannequin’s leg. The guest rooms are very simple and basic, with leaking roofs and torn sheets acting as curtains, but they do boast real furniture. The toilets are eco-friendly chemical commodes, and forget about washing off the day’s grime in this hotel: there are no showers.

The project is meant to show that, unless we make some major changes to the way we treat the world’s beaches, we will one day be surrounded by garbage wherever we go. In the words of Schult, “we create rubbish and we become rubbish. We must change the world before the world changes us.”
