San Francesco, Gothic Roman Catholic church in Lucignano, Italy

San Francesco is a Gothic church in Lucignano featuring a two-toned facade of travertine marble and pietra serena stone with a central rose window. The interior is organized by Gothic vaults and columns that guide light and create a clear spatial division.

Franciscans settled in this part of Lucignano from 1248 and presumably soon began building the convent and church, datable between the later 13th century and the early 14th. By 1289 the church was largely finished, since it hosted the ceremony of submission to Sienese rule. In the early 17th century it was remodelled in a Counter-Reformation key, with plastered walls and new stone altars; Giuseppe Castellucci's 1903 restoration recovered the medieval look and part of the frescoes. A roof collapse in 1970 closed the church until 1984.

The church's name comes from the Franciscan friars who settled here in 1248. The altars of Saints Crispino and Crispiniano held the friars' reliquaries from 1703, including the Golden Tree, now kept in the Museo di Lucignano. The poliptych by Luca di Tommè shows the Archangel Michael holding the castle of Lucignano.

The church remains an active place of worship within the Diocese of Arezzo-Cortona-Sansepolcro and is typically accessible during daylight hours. Visitors should dress respectfully and be aware that the space may be less accessible during times of worship or religious services.

The church's best-known fresco, the Triumph of Death above the altar of the Concezione, is attributed to Bartolo di Fredi or a painter close to him and dated to around 1380. Its subject became more common in the second half of the 14th century, after the Black Death of 1348. Death appears as a rider in black on a black horse before two conversing noblemen.
