Basilica of Our Lady of the Assumption, Minor basilica and parish church in Alcamo, Italy.

The Basilica of Our Lady of the Assumption is a parish church in Alcamo featuring a central nave flanked by two side aisles and a wooden ceiling in Catalan-Gothic design. The layout creates a sense of forward movement through the interior space.

The church was built after 1332, when residents of the San Vito quarter moved near the castle of the Counts of Modica, and it opened for worship in 1402. It was enlarged in 1471, between 1530 and 1558, and in 1581. Rebuilt in 1699 by Giuseppe Diamante and Angelo Italia, it received its neoclassical facade in 1786 by Emanuele Cardona. Paul VI made it a minor basilica in 1969.

The interior walls display frescoes from the 18th century that depict religious scenes and fill the church space with color and movement. These artworks shape how the building looks today and draw visitors' attention as they walk through the nave.

The church stands in the town centre, a short walk from Piazza Ciullo. The interior has a nave and two side aisles with 5 chapels in the left nave, 6 in the right and 6 near the apse; the adjoining garden holds the 1929 War Memorial by the Sciacca sculptor Bentivegna. Access is limited during services.

The bell tower with double lancet windows is the main remnant of the Catalan-Gothic church opened in 1402; it was restored in 1942. In 1954, a 3-metre statue of the Madonna was placed on it. The dome was once covered with majolica tiles, later replaced by copper plates.
