Dating back to the 9th century, the parish church of Santa Maria a Loppia is a beautiful Romanesque building with three naves. In the Middle Ages it had many chapels under its jurisdiction and exercised a strong influence until the fifteenth century, when it fell into disuse due to the wars that affected the area.
The current church is the result of the sixteenth-century reconstruction, completed by the parish priest of Barga, Jacopo Manni. Externally it has a very protruding transept, a semicircular apse and a facade marked in the lower part by blind arches. On the left rises the bell tower of the fifteenth century, with four superimposed floors of mullioned windows. On the facade there is a curious inscription engraved in a stone, VA: VA: ET OM: VA , perhaps meaning Vanitas vanitatum et omnia vanitas. Inside there is a gilded altar from the 17th century, an octagonal marble baptistery, and a painting of the Assumption of Mary.
