Why come

Castel San Pietro Terme sitson the Via Emilia, twenty kilometers east of Bologna and on the Sillaro river that marks the historic border between Emilia and Romagna. The town was founded as a Bolognese castrum in 1200, with the Cassero gateway built into the southern walls as its main access; the gateway still stands and now serves as the civic theater. The sulphurous, ferruginous and salt-bromine-iodide waters of the Terme have been documented since 1137, with the first thermal establishment built in 1870; the present complex draws on the same springs and runs year-round. Castel San Pietro joined the Cittaslow network in 2005 and the Città dell'Olio network for its hillside olive cultivation. The Santuario del Crocifisso del Piratello, on the road to Imola, holds a fifteenth-century pilgrimage shrine that drew traffic from across northern Emilia. The Conservatorio Santa Caterina, founded in 1741, is one of the older female educational institutions still active in the region.

Castel San Pietro Terme runs all twelve months because the thermal water does. Spring and autumn are the easier months for walking the centro storico and the Sillaro valley, with mild light and the olive groves on the hill above town green or harvest-coloured. June through August touches the low thirties and humid, but the spa runs longer hours in summer and the riverside frazione of Osteria Grande stays cool. November through February is the quietest stretch for the centro storico, but the Terme keeps high occupancy through the winter health-cure season. The Santuario del Piratello holds a procession in early May; the olive festival around the Cassero, late October to early November, marks the working olive year.
