Knyaz Alexander I Square is one of the most iconic spots in central Sofia. It blends historical significance, architectural heritage, and the energy of urban life. Nestled between emblematic buildings like the National Art Gallery (formerly the Royal Palace) and the Council of Ministers, this square is a venue for major public and sporting events, including the Sofia Marathon, whose start and finish lines have traditionally been located here.

History and Architectural Significance

The square is named after Prince Alexander I of Battenberg, the first prince of Bulgaria after its liberation. The Royal Palace once stood here, now home to the National Art Gallery. The square has long been a center of political and social life, and today it continues to be a cultural and tourist hotspot.

Beyond its historic role, the square is a key urban space that connects major boulevards and pedestrian areas. It’s a popular starting point for walks through downtown Sofia and offers quick access to landmarks such as Alexander Nevsky Cathedral, the National Assembly, and Sofia University “St. Kliment Ohridski”.

What to See at Knyaz Alexander I Square

The square is surrounded by buildings rich in history and cultural significance. The most notable among them is the National Art Gallery, housed in the former Royal Palace and home to a vast collection of works by Bulgarian artists. The building itself is a historical symbol of post-liberation governance.

Just steps away is the City Garden, one of Sofia’s oldest green spaces, a favorite for strolls and relaxation, and often the setting for cultural events and exhibitions.

From the square, it’s easy to reach the Alexander Nevsky Cathedral, famous for its architecture and scale, and the National Assembly, one of Sofia’s most recognized administrative buildings.

The area is also a hub of city life, featuring a mix of cafés and restaurants that combine Sofia’s modern energy with its historic charm.
