One of the nation’s five research universities, UD celebrated its centenary in 2012. The glass-ceilinged cour d’honneur of the main edifice, built in Eclectic and Neo-Baroque style, is skirted by an arcaded corridor system, whose walls are inscribed with the names of the school’s most renowned professors and former students. The fountain in the spacious French-style park in front of the building plays a special role in student tradition: Graduates are supposed to take a plunge in its pool after their finals.

In the immediate vicinity of Nagyerdei Arena, a one-of-a-kind attraction beckons from spring through fall. The multimedia fountain, or “Mist Theatre,” boasts a 30×10-m, fan-shaped curtain of water vapor which can be used as a functional movie screen to show clips of Debrecen as well as special laser installations. The more adventurous might want to try the stepping stones across the basin on sweltering summer days.

El Retiro, an iconic park in Madrid, was once reserved exclusively for Spanish royalty, but it became accessible to the public in the late 19th century. Covering 350 acres, it is one of the largest parks in the city and is often referred to as 'the lungs of Madrid' due to its vast green spaces. It's a popular spot for leisure, sports, and outdoor activities, with wide avenues and flat terrain perfect for running, cycling, and skating. You can also rent rowboats to paddle around the pond or enjoy a horse-drawn carriage ride. The park is home to several architectural and historical features, including the Velázquez Palace and the Crystal Palace, as well as remarkable sculptures and fountains, such as the statue of the Fallen Angel, the only sculpture in the world to represent the devil, Lucifer. The park also boasts a Puppet Theatre, which offers a unique program every weekend and is one of a kind in Europe.
