Rocchetta Mattei is a castle located on the Northern Apennine Mountains. It blends various eclectic styles, from medieval to moorish. It was the home of count Cesare Mattei, a scholar, politician and self-taught physician who founded electrohomeopathy, a practice founded on homeopathy. On November 5, 1850, the first stone of Rocchetta Mattei was laid, and as early as 1859 it became habitable and eventually Cesare Mattei’s permanent residence. Inside Rocchetta Mattei, the count led a life as a medieval castellan and even created a court, complete with a buffoon. The castle hosted illustrious individuals who came from everywhere to undergo Mattei’s treatment, including Ludwig III of Bavaria and Alexander II of Russia. In 1925, there was an official visit by the Prince of Piedmont. Even Fyodor Dostoevsky quotes the Count in The Brothers Karamazov, when he tells the devil he managed to recover from terrible rheumatism thanks to a book and some drops from Count Mattei. In 2006, the foundation of Cassa di Risparmio in Bologna officially announced the acquisition of Rocchetta Mattei, restored it, which ultimately led to the reopening to the public on August 9, 2015
