Corinaldo is a lovely fortified hill town, that boasts the best-preserved 15th century defensive walls in the Marche, surrounded by towers, gates and polygonal ramparts.In its medieval centre stands one of the most typical sites, the so called “Piaggia”, the one hundred Steps, leading upward to Piazza del Terreno.It’s worth wondering up and down the narrow stepped streets and visiting the Civic art gallery dedicated to Claudio Ridolfi and the shrine dedicated to St Maria Goretti, the town’s own 20th century saint, murdered in 1902 at the age of 12 by a would-be rapist whom she resisted.
