It is the oldest and most historically important center of the middle course of the Campola. The villa always followed the events of Canossa to whose community and fiefdom it belonged. In 1570 it passed to Count Bonifacio Ruggeri and in 1593 to the Counts Rondinelli. It was briefly incorporated into the fiefdom of Bedogno, established in 1605 by Duke Cesare d'Este and finally assigned to the House of Valentini of Modena who kept it until the abolition of the fiefdoms. At the end of the eighteenth century it included a population of 246 inhabitants. After the Este restoration it was part of the Municipality of S. Polo d'Enza and with the decree of the dictator Farini of 4 December 1859 it was aggregated to the new Municipality of Vezzano sul Crostolo.
The ancient church is located on a hill overlooking the small town. We can reconstruct some of its events starting from the Middle Ages. A "chapel" of Casola Canossa was donated in 1082 by Anselmo, bishop of Lucca and administrator of the bishopric of Reggio, to the monastery of Canossa. It is then remembered, with the title of S. Eufemia, among the churches dependent on this monastery in the diploma of Arrigo V of 1116, in the Bull of Pope Adrian IV of 1157 and of Pope Alexander III of 1178. Later it appears among the branches of the Pieve di Paullo. In 1443 the church was lengthened. Bishop Rangone, during his pastoral visit of 1594, ordered the restoration of the facade and roof. The building was then reduced to the form present in the second half of the 17th century. Bishop Picenardi, in 1705, found it well whitewashed and decorated. Other interventions with the arrangement of the floor and the ground around the church were carried out between the 19th and 20th centuries. The church is liturgically oriented with a simple gabled façade. The bell tower rises on the northern side with a bell chamber with mullioned windows. The interior has a single nave with three altars. Near the church stands the rectory complex with the annexed rustic building now in ruins. On the façade is a small panel signed "A. MDCCXIV- RC. LC". In front of the rectory is also notable the rural complex forming part of the church property, consisting of a typology with separate elements with a manor house, a farmer's house and a stable, presumably attributable to the 15th-16th century; several architectural details of ancient origin can be found there.
Just downstream and upstream of the town, in a short stretch, there were two mills built along the Campola stream whose current was exploited. The one downstream, towards Pecorile, is known as the Caprari mill, the one upstream as the Casola mill. Both have been transformed into civilian homes.
