Convento del Carmine, Carmelite convent in Marsala, Italy

Convento del Carmine is a Carmelite complex in Marsala made up of a church, a convent and a bell tower. The tower, rebuilt in its 18th-century form, has an octagonal plan with a stone helical staircase inside. The church entrance is preceded by a portico of three arches, the central one wider, on calcarenite columns, with Renaissance windows above.

Carmelite friars likely reached western Sicily in 1224, and from 1315 they built a church and convent outside the walls, a pilgrimage site honouring the Madonna di Trapani by Nino Pisano. In 1490 the provincial Ludovico Petrulla bought the bell tower and adjoining houses to enlarge the complex; the church was renewed after that date, and the tower took its 18th-century form, restored in 1684.

The church is also called dell'Annunziata, after the Carmelites' church rebuilt from 1490, when the older church became its sacristy and nearby houses were turned into chapels. The Petrulla family used a chapel dedicated to Saint Onophrius as its burial place, and a chapel for the Grignani held Domenico Gagini's 1490 Madonna del Popolo, now in Marsala Cathedral.

The complex stands on Piazza del Carmine, a nearly rectangular widening of a street on the old Lilibeo grid in the Annunziata district of western Marsala. The bell tower is separate from the church and convent, an uncommon arrangement in western Sicily. The baroque Palazzo Grignani faces the same square.

The octagonal bell tower was long held to be one of Lilibeo's ancient watchtowers, but recent surveys placed the Punic wall much further south, ruling out reuse of a Punic-Roman structure. Its stone helical staircase shook so much when the bell tolled "a mortorio" that people inside were frightened.
