The Église Sainte-Croix, tucked into the lower streets of the Terra Vecchia quarter near the Vieux Port, is one of the most atmospheric small churches in Bastia. It is the oratory of the Confraternité de la Sainte-Croix, a lay religious brotherhood that has maintained this building since the 15th century. The interior is furnished in an elaborate baroque style with gilded woodwork, painted panels, and the distinctive decorative character of Genoese religious art.
The church's principal treasure is the Cristo Nero — the Black Christ — a dark crucifix that legend holds was found floating in the sea offshore in 1428. Whether or not the story is literally true, the Cristo Nero has been the object of Bastia's most important religious devotion for centuries. The Good Friday procession, in which the confraternity carries the crucifix through the city in a solemn nighttime procession, is one of the most moving religious spectacles in Corsica.
