Metropol Parasol — World's Largest Wooden Structure

Metropol Parasol is a wooden structure located at La Encarnación square, in the old quarter of Seville, Spain. Designed by German architect Jürgen Mayer-Hermann, the structure resembles a grove of prefabricated wooden trees soaring 26 meters into the air. It has dimensions of 150 by 70 metres and claims to be the largest wooden structure in the world. The building is popularly known as Las Setas de la Encarnación (Incarnación's mushrooms). The Metropol Parasol actually is a device for revitalising the Plaza de la Encarnación, which was used as a parking lot for years and seen as a dead spot between more popular tourist destinations in the city. 

The structure consists of six parasols in the form of giant mushrooms, whose design is inspired by the vaults of the Cathedral of Seville and the ficus trees in nearby Plaza de Cristo de Burgos. The Parasol contains a market, shops, and a podium for concerts and events. In the basement is an Antiquarium, where Roman and Moorish remains discovered on-site are displayed in a museum. On the roof there is an open-air public plaza, shaded by the wooden parasols above and designed for public events. There are panoramic terraces, including a restaurant, offering one of the best views of the city centre.
