The impressive Vilnius University ensemble was established in 1579 and represents different architectural styles: Gothic, Renaissance, Baroque, and Classicism. The ensemble consists of thirteen enclosed courtyards, St. John's Church and the highest viewing point of the Old Town. The 68-metre high campanile offers a breathtaking view of the Old Town.

The Church of Saints Cyril and Methodius, completed in 1907, honours the 9th-century Byzantine brothers who evangelised the Slavs and are credited with creating the Cyrillic alphabet. Designed by Italian architect Ricardo Toscani, this Orthodox cathedral features a three-nave basilica with marble columns and a striking stained-glass depiction of the saints. Known for its intricate iconostasis and frescoes by renowned Bulgarian artists, the church underwent foundation repairs in 2016 and remains a significant cultural and spiritual landmark.

Nessebar, a city-museum and UNESCO World Heritage Site, is another marvellous day trip from Burgas, located just 35 kilometres away. This ancient town, often called the "Pearl of the Black Sea", sits on a small peninsula connected to the mainland by a narrow causeway, offering stunning sea views on both sides. Its cobblestone streets wind through a historic centre filled with over a millennium of architectural treasures, including the Church of St. Sofia, a 5th-century basilica, and other medieval churches like St. John the Baptist and St. Stephen. The Old Town, a maze of narrow lanes and 18th-century houses, invites leisurely exploration, with artisan shops and street vendors adding to its charm. Nessebar was once a Thracian settlement and later a Greek colony, playing a key role in the development of trade and culture in the Black Sea region. Its unique blend of ancient ruins, Byzantine churches, and a lively atmosphere makes it a captivating destination for history enthusiasts and casual vacationers.
