The most architectonically important edifice is the Parish Church of Saint John the Evangelist
, edified in 1828 on the foundations of an earlier 16th century church (the first document mentioning dates back to 975). Among the works of art present on the inside of the church there is an Holy Cross painted by Enrico di Tedice
in the second half of the 13th century (but it was originally in the church of Castellare).
On the left side of the church there is theoratory of the Company of the Holy Sacrament – now used as a warehouse. On the outside of this ancient chapel there is a marble relief representing the Annunciation, dated 1639. In close proximity to the Parish church we can see theoratory of San Rocco , that was constructed in 1635 according to the will of Tedda Cascina. It is currently used as a warehouse. Along the streets of the village, there are three 16th century marble tabernacles representing the Madonna with the Infant. On the Piazza della Repubblica, there is a Memorial of World War I, made by Arturo Tomagnini.
In the surroundings there are many outstanding palaces dating back to the 18th-19th century, among which Villa Lupi (now Conti) and Villa Rossoni-Mastiani, both of them provided with private chapels.
On top of the hill which dominates the village we can see theOratory of Santa Croce in Castellare
, probably built in 1656 on the foundations of an earlier edifice (a castle, according to some theories). It was completely rebuilt in 1723 and then again in 1818.
In May 2017, an accidental explosion seriously damaged the Castellare oratory.
