San Pier Maggiore is an originally Romanesque-style, former Roman Catholic church in Pistoia, region of Tuscany, Italy.
The central portal's architrave is attributed to the workshop of Guido da Como, and depicts a "Jesus Giving the Keys to St Peter, with the Virgin and the Apostles".
The façade has maintained the original Romanesque appearance, and, like the nearby church of San Bartolomeo in Pantano, is divided into five compartments with bichrome decoration.
[1] Today the church is deconsecrated, the interior artwork has been moved, and the former convent now houses a State Institute of Arts, the Liceo Artistico Petrocchi.
Of historical interest is that a newly appointed bishop to Pistoia, arriving to town via Porta Lucchese, in a ceremony in this church, would have a mystical marriage to the abbess of the Benedictine convent, and then move to the cathedral to take his post.
