Maniace (Italian: Maniace; Sicilian: Maniaci) is a comune (municipality) in the Metropolitan City of Catania in the Italian region Sicily, located about 130 kilometres (81 mi) east of Palermo and about 45 kilometres (28 mi) northwest of Catania.

The municipality bears the name of George Maniakes (Greek: Γεώργιος Μανιάκης; Italian: Giorgio Maniace), a Byzantine general of the 11th century and catepan of Italy, known for his victories against the Arabs in Sicily.

The nave and magnificent West Door (main entrance) of the ancient Norman-style (called Romanesque in Italy) monastic church, dedicated to Santa Maria, survives with part of the cloister, as one side of the rectangular courtyard of the manorial buildings, in the centre of which survives an ancient stone well.

[4] The former apse, chancel and transept tower of the church (roughly the entire eastern half) is missing, believed to have collapsed during the terrible earthquake of 1693,[5] with the site partly built over later by a new granary building in which the foundations of the triple apse were recently discovered.

The church with the other adjoining manorial buildings were restored and reconstructed in 1800 on the order of Admiral Nelson, 1st Duke of Bronte, who never set foot on his estate, having been killed 5 years later in heroic circumstances during the Battle of Trafalgar.
