Pieve di Sant'Antonino a Socana, Medieval church in Pieve a Socana, Italy

Pieve di Sant'Antonino a Socana is a church in the Casentino valley, documented from 1004. Its facade with sloping gables dates to the 16th century, when the building was shortened to three of its original six bays. Inside, round arches on rectangular and square piers carved with interlace and palmettes survive, and the last bay with the large apse is built in alberese stone.

The religious building stands atop the remains of an Etruscan sanctuary dating to the 5th century BC. Excavations in the 1970s uncovered a preserved sandstone altar that testifies to the site's ancient sacred roots.

The name Socana likely comes from the Etruscan personal name Saucni, and the nearby stream Rassina from Rasenna, the Etruscans' own name for themselves. The church was built facing opposite the Etruscan sanctuary, and beside the rectangular piers of the nave the bases of the earlier church's columns are still visible.

The church stands in the hamlet of Pieve a Socana, in the municipality of Castel Focognano, on the left bank of the Arno in the southern Casentino. The Etruscan altar and sacred enclosure lie behind the apse, reached by walking around the building; the ground there is unpaved. The bell tower keeps its cylindrical base but its belfry cell was rebuilt.

The Etruscan altar behind the apse was partly rebuilt: blocks found in surrounding walls were reassembled with lead clamps, and it was last maintained in 2015. Its moulded profile resembles the altar of Temple C at Misa near Marzabotto, evidence of ties between the Casentino and Etruria Padana.
