St. Mary's Cathedral, Neoclassical cathedral in central Chiclayo, Peru

St. Mary's Cathedral stands on Chiclayo's main square, a pale yellow neoclassical building with white trim. Six tall white columns form a portico beneath a triangular pediment, flanked by two bell towers with domed tops and crosses; the right tower carries a round clock face. Three arched doorways open below the portico, and the crossing is topped by a large dome.

The design dates from 1869, when plans were commissioned from Gustave Eiffel. Work stopped in 1871 for lack of funds and resumed on 13 February 1928 after the Congress of the Republic allocated money; it was completed in 1939. The cathedral replaced the 16th-century Iglesia Matriz, demolished in 1961, as the diocesan seat.

The cathedral serves as a center of worship for the community and displays an image of Santa Maria de los Valles de Chiclayo on its portal, honoring the Franciscan friars who founded the settlement.

Visitors should come during daytime hours when the building is open to the public and the architecture is best visible in natural light. The central location makes it easy to reach on foot or by short rides.

The four bells are named "Ave Maria", "Asumpta", "Mater Dei" and "Gratia Plena". Cast in Germany, they reached the Port of Pimentel, travelled by the Pomalca railway and were hauled from the Colón Street station to the cathedral on a truck-drawn platform.
