Metropol Parasol is a primarily wooden building located at La Encarnación square, in the old quarter of Seville, Spain. It was designed by the German architect Jürgen Mayer-Hermann and completed in April 2011. It has dimensions of 150 by 70 metres (490 by 230 ft) and an approximate height of 26 metres (85 ft) and claims to be the largest wooden structure in the world. Its appearance, location, and delays and cost overruns in construction resulted in much public controversy. The building is popularly known as Las Setas de la Encarnación (Encarnación's mushrooms).
