Église Saint-Martin de Montlouis, Romanesque church in Montlouis, France.

Église Saint-Martin de Montlouis is a Romanesque church of light beige stone with a single nave and no side aisles, its flat-ended choir separated from the nave by a double band of round-arched moulding. The massive square bell tower stands on the south side, pierced under the belfry by twin pointed openings divided by a column. The west facade has three portals, two of them walled up, and a round window above the central doorway.

Construction began in the 12th century and the building received official protection as a historical monument in 1926. This recognition marked its importance for the region's heritage.

On the north capital of the central doorway, carved cat heads grip stems of stylised palmettes, with a ribbon below holding further palmettes reaching down to the astragalus. François Deshoulières called this a typically Berrichon formula, a local carving tradition visible to visitors at the entrance.

The building sits in the village center of Montlouis and is easily spotted from the main street. Visitors should keep in mind that interior access may be limited depending on the time of day and local arrangements.
