"Rubbish hotel" booked up for Spanish tourism fair

German sculptor H.A. Shult used 12 tonnes of recycled junk to build the hotel in central Madrid's Callao Square and draw attention to the amount of flotsam spoiling Europe's beaches.

"We must know and we must understand that the oceans are the biggest garbage dumps of the world," Schult told Reuters.

His Corona Extra Save the Beach Hotel opened its doors on January 19 and operators say its five double rooms have been fully booked for the four days in which it will be taking guests.

"The world is a hotel and so as a parable, I show the world as a hotel, and this world we only have rented and we have to realize that we in this time fill up the whole world with garbage," Shult said outside the hotel.

Schult has been getting support from some pretty famous patrons, including Danish model Helena Christensen -- who has spent a night in the hotel -- French explorer Alexandra Cousteau and jewelry designer Jade Jagger.
