The imposing and gentle belfry of this ancient church stands stately in the heart of the historical quarter of Albergheria, near the picturesque Capo Market, and was formerly a medieval vigil tower, built in the 13th Century to help defend the town walls. The elegant mullioned windows with bi-chrome lava stone inlays typical of Gothic-Catalan style were added in the 15th Century. The tower was turned into a belfry for the Church of San Nicolò in the 16th Century and nowadays offers to visitors an unforgettable view of the town. The church itself dates back to the 13th Century and was built at the bequest of the powerful Sclafani family. It still has severe exteriors, with a facade adorned only by a baroque aedicule (shrine) enclosing a beautiful 18th-century statue of the Immaculate Conception. The interiors look neoclassic as they were hugely renewed in the 18th Century. Noteworthy are the dramatic 16th-century crucifix on the right wing of the transept, and a neoclassical painting representing San Nicolò on the opposite wall. Call ahead for hours.
