Located by the river, it was certainly occupied from the Gallo-Roman massacre of the Helvetii in 58 BC, and some remains found its name Villa Maximico we suggest.
Officially Messimy appears in the scriptures where the year 960 or a Sobus Sablon and his wife gave Valencia the Abbey of Cluny property they owned Messimy (vineyards, meadows, woods), and this for the rest their souls.
It is mentioned that in 1006 was the chief place of Messimy Ager.
Its name was changed in centuries. Written in Latin "Meyssimacy there Dombis" (Messimy-en-Dombes), he became Messimy-sur-Saône March 7, 1983.
Farming village in the principality of Dombes, it was annexed to France March 28, 1762.
The church dedicated to St. Peter was confirmed Ainay (Church of Lyon) February 26, 1153. The building was enlarged over the centuries and only the apse is original.
Messimy lordship appears in the early 13th century. He noted the Chabeu, lord of Saint-Trivier-sur-Moignans and returned to a family named Messimy at the end of the 13th century.
Sold in 1313 to the Sire de Beaujeu, it changed ownership several times and became County in 1699 in favor of Antoine Desrioux.
A second fief was divided village lands, Lordship of Montbrian (fortified house Mondemangue of the 15th century). This property became the County to Daniel Leviste Brindas in 1756. Descendants of these two lordships were guillotined in troubled times of 1789.
Of agricultural (livestock and cereal crops) Messimy also had many vineyards.
Distant 37 kilometers from Lyon and serviced by a main road, its location along the Saône won him the favor of Lyon in 1940. He built homes or restored old buildings. Thus Messimy-sur-Saône gradually lost its agricultural and became what it is today.
