Saints John and Ermolao, or Pieve di Santi Giovanni ed Ermolao is a Romanesque-style, Roman Catholic parish church, located in La Pieve, Calci, some 10 km outside Pisa, region of Tuscany, Italy.
[2] It includes the depiction of the river Jordan in human form, and the inclusion of angel statues.
Similar classical forms characterize the interior of the basilica, which is divided into three naves by columns surmounted by neo-corinthian capitals.
A short distance from the walls of the church, on the south side, is a majestic gateway arch.
The presence of two windows on the north and east sides that are tall and narrow with wide internal splay, features typically loopholes included for archers, are partial evidence for the tower's defensive role, along with the structure's 9 meter width.
