The Saint André church (13th-15th-16th centuries)
In the 7th century, the Benedictine abbey of Bonneval created a priory-curate. Its existence is confirmed by a bull from Pope Gregory second half of the 16th century.
In 1793 the church was desecrated and transformed into wine and spirits warehouses.
In 1801, the church was returned to worship and changed diocese: from the diocese of Chartres, to which it belonged before the Revolution, it passed to the diocese of Orléans, notably for reasons of distance: Chartres is 48 km from Patay then that Orléans is only 27 km away.
The church is 30 m long and 17 m wide. The oldest parts are located near the large porch (13th century). One of the pillars of the nave is decorated with a vestige of Danse Macabre from the mid-15th century. A small masonry door on the right communicated with the old priory, of which ruins remain to the south of the church. The choir dates from the 14th century; the apse wall was decorated with paintings at the end of the 19th century, the chapels were then redeveloped and equipped with new stained glass windows. The keystones of the large nave were made from casts taken from the figurines which adorn the Thesis Room of the University of Orléans, built in 1411.
The bell tower, located to the north of the choir, would be an old watchtower. Its pinnacles and eight openings were made after the Wars of Religion. The four bells were melted in 1868. The largest was cracked by a Prussian shell in 1870 and was recast in 1871. Since that year, Ernestine (809 kg, 1 m 12 in diameter at the base, sounding the F), Gabrielle (550 kg, 0.981 m in diameter, sounding the ground), Anne (398 kg, 0.573 m in diameter) and Marie (222 kg, 0.724 m in diameter, sounding the C) give rhythm to the daily life of the small town of Patay, old Beauceron railway junction.
On August 15, 1944, an ammunition train was blown up at Patay station. The station was blown up, except for the carriage shed, and all the windows in the town were shattered. Luckily, a providential storm limited the damage. The only two stained glass windows that survived the explosion are those on the right side aisle which date from 1930 and relate the communion of Joan of Arc in the Patay church in 1429.
The church was listed as a Historic Monument in 1925 by decree of October 6, 1925.
