Convento di Certomondo, Romanesque convent in Poppi, Italy.

Convento di Certomondo is a medieval convent in Poppi with a simple facade featuring a round window and a portal crowned by a rounded arch. The complex contains plain structures arranged around a central courtyard that once housed the religious community.

Guido Novello Guidi, count of Poppi and Modigliana, founded the convent to commemorate the Ghibelline victory at Montaperti in 1260. After the battle of Campaldino, Bishop Guglielmino degli Ubertini was buried inside it, while the fallen of the battle were laid in large pits nearby.

The church's best-known work is Neri di Bicci's Annunciation, commissioned in 1465 and finished the following year; two side panels with Saints Catherine, Anthony of Padua, John the Evangelist, Francis, Lawrence and Louis of Toulouse are now in the Musée du Petit Palais in Avignon. Fragments of 14th-century frescoes, including a Virgin enthroned with saints, remain, along with two 18th-century canvases attributed to Andrea Bighi, a pupil of Pier Dandini.

Access to the convent is limited as the religious spaces are not regularly open to visitors, though group visits can be arranged through a reception area. It is best to contact ahead or arrange a guided tour to see the interior.

The church's 1465 Annunciation by Neri di Bicci originally had two side panels with Saints Catherine, Anthony of Padua, John the Evangelist, Francis, Lawrence and Louis of Toulouse; these are now in the Musée du Petit Palais in Avignon, so the altarpiece is split between Tuscany and France.
