Situated at the crossroads of ancient trade routes, the capital of Thuringia has always been a meeting place and home of important intellectuals and a magnet for visitors from around the world.Erfurt was once lauded as the City of Towers in reference to the lofty spires of the city's 25 parish churches, 15 abbeys and monasteries and ten chapels that stretch their way up to the heavens. Particularly striking are St. Mary's Cathedral and the Church of St. Severus, as together these two masterful examples of German Gothic design form an architectural ensemble like no other in Europe. Nowadays, the church towers cast their shadows over the lovingly restored timbered-framed houses and beautiful Renaissance buildings of the historical city centre, where one of Germany's finest open-air theatre events, the Cathedral Steps Festival, takes place every year.
