San Pietro, Medieval church in historic centre of Grosseto, Italy.

San Pietro is a small medieval church on Corso Carducci in Grosseto, its Romanesque semicircular apse built of stone with visible travertine blocks. A 17th-century brick bell tower with a small dome rises to the right of the apse on a stone base. The facade has a portal flanked by pilasters and four early medieval bas-reliefs.

The first written record dates to 1188, though excavations uncovered structural elements from the 9th century. The building evolved from its early medieval origins into a significant religious structure incorporating baroque features over time.

The facade displays four bas-relief panels from Byzantine and early medieval times with figures, animals, and decorative motifs. These artworks come from different periods and tell the story of the place's long religious past.

The building sits on Corso Carducci, the main street cutting through the historic center, making it easy to find on foot. From this location you can easily walk to nearby churches including Bigi and San Francesco.

Since 2010 the Romanian Orthodox Church has held services here, adding a contemporary layer to its religious role. This modern use brings different faith communities together within a historic structure.
