It is difficult to establish a rather precise date concerning the building of the Pieve di Montemignaio (= Parish Church of Montemignaio). From several documents and some architectural characteristics it can be supposed to be at the beginning of the XII century. The construction of the church went on for a long time; this is easy to understand thanks to the different styles of the architectural elements: columns with capitals in a part of the church, plastered and frescoed pillars in another. The capitals on the columns have different styles. There are certain elements that remind the Gothic architecture. This variability of styles is also due to different interventions of consolidation and restoring of certain structural parts of the church that passed in the centuries. Despite this the Parish Church of Montemignaio is to be considered a remarkable example of Romanesque architecture in the Casentino. The workers who worked to the construction of the building were surely the same or at least came from the same school as the ones who built the other three important Romanesque parish churches of the Northern Casentino: Romena, Stia and Strada. In these last ones you can find building conceptions and architectural and decorative elements similar to Montemignaio, even done in a more refined way.
In the Parish Church of Santa Maria Assunta several high-level works of art are preserved. You can look at all of them and read their explanations in the photographic gallery of this page.
