Once Shenzhen's tallest skyscraper, Di Wang Building is more than just an architectural feat—it’s a symbol of the city’s rapid growth. Take a 50-second ride to the 68th-floor observation deck, where you'll be treated to panoramic views: Shenzhen’s ever-expanding skyline on one side and a glimpse of Hong Kong on the other. Once holding the world record for construction speed (an impressive 2.5 days per floor), this building is a testament to the city’s ambition. Although newer skyscrapers now tower over it, Di Wang remains a must-visit for those wanting a bird's-eye view of Shenzhen's dynamic urban landscape, especially when the sun sets and the skyline lights up.

With exhibits ranging from model boats to fish skeletons and sixteen aquariums, this is a superb museum about all things nautical. Look out for the two-headed sardine and the famous 60-ton whale skeleton. If after your visit you get hungry, there's a on-site restaurant with bay views.

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.
