The Opera Square Festival (Opernplatzfest) in Frankfurt is held outside one of the city's most beautiful sights, the Alte Oper concert hall. The festival, which runs until 29 June 2012, is a homage to the Hessen city and its vibrant cultural scene. It features street performers, stage shows and piano concerts, plus a great selection of delicious food and drink. Fantastic entertainment in the heart of the city!
