The Schloss Erlangen is a residence in Erlangen, built between 1700 and 1704 by George William, Margrave of Brandenburg-Bayreuth. Work was initially led by Antonio della Porta and after his death in 1702 by Gottfried von Gedeler. It was the first baroque building built from scratch in Franconia.
Christian Ernst moved his third wife Margravine Elisabeth Sophie of Brandenburg into the Schloss in 1703 when it was still incomplete, giving it its initial name, the Elisabethenburg. Behind it was a 280 metre wide and 550 metre long garden with an orangery, the Konkordienkirche, the Hugenottenbrunnen fountain, an equestrian statue and a now-lost Sylvan theater.
