Rocchetta Mattei

Rocchetta Mattei is a striking 19th-century castle situated on a rocky spur above the Reno valley near Riola, in the municipality of Grizzana Morandi, Emilia-Romagna, Italy. Construction began in 1850 under the direction of Count Cesare Mattei, who designed the structure on the ruins of the medieval Rocca di Savignano. While the main phase of building was completed in 1875, alterations continued into the early 20th century. The edifice is celebrated as one of Italy's most significant examples of eclectic architecture, seamlessly blending neo-medieval forms, Moorish Revival details, and Art Nouveau elements into a deliberately labyrinthine layout that reflects the unique vision of its creator.

Historically, the castle served a dual purpose as both a private residence and the headquarters for Mattei's controversial alternative medical system known as electrohomeopathy. This unusual function attracted patients and visitors from across Europe during the late 19th century, embedding the site deeply in the region's cultural and medical history. The location itself holds strategic importance, having previously been a fortified point linked to trans-Apennine routes and Bolognese territorial control before Mattei transformed it into his eccentric masterpiece.

Following a period of decline, the complex was acquired by the Fondazione Cassa di Risparmio in Bologna in 2005. The foundation undertook an extensive restoration programme to preserve the intricate interiors and structural integrity of the building. Reopened to the public in 2015, Rocchetta Mattei now operates as a museum and cultural venue. It has quickly become one of the most visited heritage sites in the Emilia-Romagna Apennines, drawing over 73,000 visitors annually who come to explore its unique architectural fusion and fascinating past.
