The Parish Church of San Giovanni and Santa Maria Assunta is linked to the birth of the village of Cascina during the Middle Ages when this Romanesque church was built on the territory. The building dates back to the end of the 11th century and vaunts three naves, divided by monolithic columns of marble, pink granite and cipollino marble, detailed with Corinthian capitals.
The main feature of the façade is the division into five arches, recessed rhombuses and three portals. The upper part is embellished with marble details and three small arches. The tympanum has a marble cross in the centre with two oculi on either side.
Inside the church there is a terracotta by Benedetto da Maiano depicting the Madonna and Child along with a Romanesque font and a fourteenth-century fresco.
