Zum Rothen Haus, a listed building that has served for over 200 years as an inn, is where Mozart’s family stayed in 1763. On 15 July, the seven-year-old Wolfgang Amadeus Mozart gave a concert at the electoral court, together with his older sister Nannerl. His father, Leopold Mozart, reported in one of his famous letters that the children had “set the whole of Schwetzingen astir.”
