In 1996, American artist James Turrell designed the Celestial Vault to showcase the sky in all its glory using an innovative astronomical optical illusion. In the centre of this grassy artificial crater, there is a stone bench on which visitors can lie to observe the sky as a curved dome, emphasising the way light affects how we perceive things and inviting those willing to challenge their own perceptions.

Nagyerdei Park is the home of Hungary’s most modern sports arenas. The brand new, state-of-the-art arena, Nagyerdei Stadium, was inaugurated in 2014. With a seating capacity of 20,000, it promises to become a fantastic venue of competitive team events and individual training sessions as well as concerts and other programs of cultural interest. The stadium’s unique architectural features boast a spectacular “suspension sidewalk.” Complete with a running track, the 1,100-m-long structure skirts the entire building at a height of several meters. This will make joggers feel that they do altitude training smack in the middle of the flattest region in Hungary.

The Film Museum in the Albertina is a must in Vienna for every film enthusiast, serving as a cinematheque and an archive for a collection ranging from the origins of film history to the present days; make sure to check the schedule on their website to see what is currently being screened, as this isn't a "museum" in the traditional sense of the word, but more of a historic cinema. National and international films are screened all year round, with changing retrospectives and individual presentations offered to the public. The Film Museum also boasts the widest collection of film literature in the country, as well as a selection of cinema-related photos, posters and periodicals.

Debrecen’s symbol is one of the nation’s largest Reformed churches, a building of major historic significance. It was here that Lajos Kossuth read out the Declaration of Independence on April 14, 1849. The wing chair used by the Regent-President on that glorious occasion is one of the church’s most precious relics. The main structure has been rebuilt several times. Today’s familiar Classicist form was developed after the great fire of 1802. You can enjoy magnificent views of the city from the top of the towers, or the steel bridge behind the tympanum. If you are courageous enough to attempt the steep climb up, your added bonus will be a spectacular close-up of the 5.6-ton Rákóczi Bell. In addition to regular services, exhibits of religious history, organ concerts and other musical events are also on the schedule. The church has held the status of national monument since 2013.
