Prince Alexander of Battenberg Square

Prince Alexander I Square, often called simply Battenberg Square is the largest square of Sofia, the capital of Bulgaria. It is named after Alexander Joseph of Battenberg (Alexander I of Bulgaria), the first prince of modern Bulgaria, and is arguably the most suitable place in Sofia for major open-air concerts such as the concert series "Opera on the Square", demonstrations, parades (including the military parade on St George's Day) and other large-scale events.
