San Quirico with its characteristic buildings in pietra serena, rich in portals and finishes, it is located at 529 meters above sea level with houses typically perched on the hill.

What to see in San Quirico: The remains of the 13th-century walls of San Quirico, including a hexagonal watchtower, stand out. In the lower part of the village are the imposing bell tower and the beautiful Romanesque church of Saints Andrew and Lucy. Built in a dominant position over the village, it has three naves. Inside the church, the remains of the ancient structure are still clearly visible. The 15th-century baptismal font in pietra serena is stunning. Inside, there are five altars, a baptismal font decorated with cornucopias and rose windows (1441-1497), and it is enriched by a large gray stone arch carved with plant motifs and the symbols of the four Evangelists (late 15th century), and a pulpit, all made of pietra serena. In front of the main altar are two precious wooden sculptures depicting Saint Andrew and Saint Lucy, similar to the work of Francesco di Valdambrino, executed by an unknown artist in the first decade of the fifteenth century.
