The Church of Sant'Oliva, located at the majestic entrance of Piazza Ciullo, stands as a historical and cultural emblem, whose roots extend until 1533. This architectural jewel, after being rebuilt in 1724 under the visionary guidance of the architect from Trapani Giovan Biagio Amico, an illustrious architect at the service of the Real Patrimonio and the Senate of Palermo, continues to bear witness to the artistic and spiritual richness of the region.

Inside, the high altar is majestically adorned with a painting from 1639 by the incomparable Pietro Novelli, entitled "The Souls of Purgatory". This work, imbued with meaning and artistic mastery, invites the faithful to a deep reflection on redemption and the afterlife, demonstrating the ability of art to elevate the spirit and stimulate thought.

The altars, real works of art, are embellished with beautiful polychrome marble skilfully carved by Mariano and Simone Pennino, offering an exhibition of beauty and craftsmanship. These decorative elements, together with the refined architecture, create an environment of devotion and admiration.

Among the other wonders that adorn the interior of the church, stand out two marble sculptures of the Gaginesca school, depicting "San Luca and Sant'Angelo" and a marble group depicting the Annunciation, masterpieces executed in 1545 by Antonino and Giacomo Gagini. In addition, the marble statue of Sant'Oliva, a work executed by Antonello Gagini, stands out as one of the most sublime expressions of sculptural art, revealing the deep devotion and extraordinary talent of the artist.

Despite the hardships suffered, such as the serious damage following the earthquake of 1968 and the devastating fire in 1987, the roof of the church was rebuilt a few years later, a symbol of the resilience and hope that animate the community. Today, the Church of Sant'Oliva not only represents a spiritual point of reference for the faithful but also an artistic and historical treasure that continues to inspire admiration and reflection in visitors and devotees.
