This magnificent 19th-century building opened in 1892 and is regarded as an emblematic of the city. Teatro Campoamor is also the venue for the annual Prince of Asturias prize ceremony and for the city’s annual opera season and the Zarzuela music festival. The theatre’s elegant interior was influenced by the Teatro de la Comedia in Madrid and is opulently decorated in scarlet, gold and red. On the first floor you can find the statue of Ramón de Campoamor, the Asturian poet after whom the theatre is named.

The National Museum Bangkok is the biggest museum in Southeast Asia and a great stop, alongside the Museum of Siam, if you want to understand Thai history and art. It’s spread across several buildings, showcasing everything from ancient sculptures and royal regalia to traditional costumes and ceramics. The collection can feel a bit overwhelming, so it’s worth focusing on the highlights—like the giant Buddha statues and the Bangkok-period royal artefacts. Guided tours are available if you want the backstory behind the displays, but wandering on your own gives a good sense of Thailand’s past at your own pace.

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.

During the 9th century this was the largest church in Spain and although now dwarfed by later and greater buildings, it remains of great significance in the history of Spanish religious architecture. The church is well worth a visit, especially for its magnificent array of gorgeously coloured murals.
