St. Denis Cathedral, Réunion, Roman Catholic cathedral in Saint-Denis, Réunion.

St. Denis Cathedral is a white stone church in central Saint-Denis, built from 1829 to 1832 to plans by the engineer Paradis. Its symmetrical facade is divided into three bays by four round arches on columns, with a dark red double door sheltered by a prostyle portico added in 1863. Above the arches, a terracotta relief panel made by the Virebent factory of Launaguet in 1863 depicts the martyrdom of Saint Denis; a square tower with a louvered opening and a stone cross rises behind.

Construction of the cathedral began in 1829 and replaced an earlier 18th-century church that had served the community for generations. The building was completed in 1832 and underwent further modifications in the following decades.

The cathedral is dedicated to Saint Denis, the saint after whom the city is named, and serves as the episcopal seat of the Diocese of Saint-Denis-de-La Réunion. Its terracotta pediment, ordered in 1863 from the Virebent manufactory in Launaguet, shows the martyrdom of Saint Denis. The stained glass was made by master glassmaker Henri Martin-Granel.

The cathedral is located in the heart of Saint-Denis and is easy to reach on foot from most areas of the city. Visitors should come during daylight hours to see the windows properly lit and to experience the interior in natural light.

Artist Henri Martin-Granel created custom-designed stained glass windows specifically for this cathedral, making them a distinctive artistic contribution to the building. The windows were crafted with particular attention to artistic detail and biblical storytelling.
