Spanning the majestic Danube River, the Széchenyi Chain Bridge stands as an iconic symbol of the city's grandeur and architectural prowess. Completed in 1849, it was the first permanent bridge to connect the Buda and Pest sides of the city. Designed by English engineer William Tierney Clark and later modified by Scottish engineer Adam Clark, the bridge's chain-link structure and ornate stone lions guarding its entrances evoke a sense of timeless elegance and pride. The lions guarding the bridge are also connected to the first suicide that happened here, committed by their architect upon the realisation that he had forgotten about the tongues of the animals.

Oviedo’s Cathedral combines Gothic, Baroque and Renaissance elements. Its 15th-century spire looms over a medieval basilica built by the first prince of Asturias. The cathedral as a whole was finally completed in the 16th century, after more than 250 years of construction work. The main altarpiece, depicting the life of Christ, is in Flemish Gothic style. The cloister is home to the Diocesan Museum, with a number of important archaeological relics.

Situated at the end of Andrássy Avenue, Heroes' Square is one of Budapest's most iconic landmarks. Dominated by the Millennium Monument, it pays homage to Hungary's history and leaders. It is flanked by the Museum of Fine Arts and the Palace of Art, and if you continue your way past the wall of sculptures, you'll reach City Park with Vajdahunyad Castle.

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.
