Sofia Ancient Serdica Archaeological Complex

The Alexander Nevsky Cathedral is a local landmark in the Bulgarian capital of Sofia. This large cathedral was built in the neo-Byzantine style, and its lavish design elements make it one of the most striking and photogenic buildings in the city.

The National Palace of Culture (NDK) is the largest multi-functional conference and exhibition center in south-eastern Europe. It opened back in 1981 to celebrate Bulgaria's 1300th anniversary. The palace was the suggestion of Lyudmila Zhivkova (daughter of former Bulgarian communist leader Todor Zhivkov) and was completed by a team of Bulgarian and international architects. The landscaping of Bulgaria Square in front of the NDK has been subject to a modern redesign and is a hub of activity every day. Inside the building, which has hosted concerts by the likes of Sting, Anastacia, and Mark Knopfler, there are 80 monumental artworks in the halls and foyers, which you can see by joining a National Palace of Culture guided tour.

The National Museum of Military History in Sofia, in various guises and locations, has been operating for over 100 years. The museum, now found in central Sofia, houses impressive military antiques like missiles and tanks as part of an open-air display. It also boasts a comprehensive indoor collection of military memorabilia and historical exhibits, detailing Bulgaria's military stories across thousands of years.
