The church was elevated to the status of a collegiate church in 1620.
The building features a distinct 'hall church' design, where the side aisles are nearly as high as the central nave.
The granite used in the construction was sourced from local regional quarries, contributing to its distinct grey aesthetic.
The current bell tower was reconstructed in the 19th century following a structural collapse.
It contains a notable collection of 15th-century stained glass windows that depict religious and local figures.
The Collégiale Saint-Aubin is the historic heart of the walled town of Guérande, serving as a primary example of Gothic architecture in the Loire-Atlantique region. The current structure, dating largely from the 15th and 16th centuries, was built upon the foundations of several earlier religious buildings. It is classified as a Monument Historique. The church is noted for its high-gabled roof and its characteristic granite masonry, typical of the Breton architectural tradition. Its interior houses significant historical artifacts, including an 18th-century organ and various carved stone elements. The site functions as a place of worship for the local Catholic parish. It remains a focal point for the town's urban layout, situated near the ramparts of the medieval center.
