The church was constructed specifically to replace an earlier structure destroyed during the 1693 earthquake.
The dome's design allows for a clear view of the Via Etnea, the city's primary north-south artery.
Its interior was designed to reflect light, creating a distinctively bright atmosphere compared to the nearby black basalt cathedrals.
The church was formally opened to the public for dome visits relatively recently, having served strictly as an active place of worship for centuries.
The facade is concave, a signature design element of Vaccarini meant to complement the shape of the Piazza del Duomo.
The Chiesa della Badia di Sant'Agata is a prime example of Sicilian Baroque architecture, designed by architect Giovanni Battista Vaccarini following the 1693 earthquake. The church features an octagonal dome that provides one of the few high-altitude, 360-degree panoramic views of Catania's historic center and Mount Etna. Visitors access the dome via a restored staircase that reveals the building's structural timber and brickwork. The interior is characterized by its bright, white-stucco finish, intentionally contrasting with the darker lava stone common in other Catanese churches. It is dedicated to Saint Agatha, the patron saint of the city. The building sits directly opposite the Catania Cathedral on the main axis of the city.
The terrace at the very top of the dome, offering a panoramic view of the cathedral dome and Mount Etna.
Climb to the dome roof for the best unobstructed view of Mount Etna.
Visit the interior floor level first to appreciate the contrast between the white stucco and the ornate altar before heading up to the dome.
Do not attempt the dome climb if you have limited mobility, as the original narrow staircases are steep and restricted.
The dome access may be restricted during inclement weather for safety.
Modest clothing covering shoulders and knees is required for entry; hats should be removed.
