Al-Masmak Palace is a clay and mud-brick fortress whose pivotal role in Saudi history belies its modest scale. Built around 1865, it was the site of the daring 1902 raid that led to the recapture of Riyadh, a foundational event for the modern kingdom. The spearhead from that assault remains embedded in its main gate. Today, the palace functions as a museum, its former residential quarters and majlis displaying historical photographs, weapons, and multimedia exhibits that chronicle the story of the nation's unification.

Home to a large Chinese population, it would be only appropriate for Lima to have its own version of a Chinatown. This is the place where visitors come to try the authentic Chifa, the Chinese-Peruvian fusion cuisine. However, keep in mind that this is not like your typical Chinatown: it is smaller, rather chaotic and somewhat rough around the edges. But if you feel like venturing into the hustle and bustle of this neighbourhood, you'll be rewarded with traditional dim sum, Peking duck and many other Asian delights.

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.

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.
