Huismes was called in the 10th century, Oximensis Villa, and Oxima in the 11th century. The alleged resemblance between this last term and “octava” gave rise to the legend which reports that Saint Gatien founded in Huismes the eighth church built by him in Touraine.
The choir, dating from the 12th century, has been classified as a historic monument since 1913. The bell tower is built on a massive square tower, the base of which is Romanesque, the upper part dates from the 13th century. The covered passage known as the deanery dates from the 16th century and, like the bell tower, has been listed in the supplementary inventory of historic monuments since 1940.
Dating from the 12th century, with the exception of the nave, restored in the 19th century and increased by an aisle to the north, the church has a belfry bell tower with a cylindrical tower housing a stairwell to access the bells. .
This church was enlarged in the 19th century and at the beginning of the 20th century by the addition of an aisle, without respecting the harmony of the old building. It nevertheless deserves attention because it includes many details, both historical and architectural. The capitals, supports of the nave and the choir are remarkable. Characters, monsters and animals are represented in symbolic scenes.
This parish formed a castellany which was given by Charles the Simple to the chapter of the church of Tours, a donation which was confirmed in 1157 by Louis VII. The seigniorial residence, known as the Doyenné, was fortified by walls lined with a moat crossed by a drawbridge. In this enclosure were the church and the presbytery. These fortifications, as well as a keep, have disappeared and the buildings of the deanery have been very modernized.
