Suardi Chapel, Renaissance fresco cycle in Suardi Oratory, Trescore Balneario, Italy.

Suardi Chapel is an oratory decorated with a series of connected wall paintings showing saints, biblical figures, and scenes set against landscape backgrounds. The frescoes cover the full wall surfaces and display complex compositions with many figures and architectural details.

The chapel existed since the 15th century on the road through Val Cavallina linking Bergamo to Lake Iseo. Around 1523 count Giovan Battista Suardi commissioned Lorenzo Lotto to fresco the restored oratory, hoping to avert a flood astrologers predicted for February 1524 and to counter Lutheranism spread by the Landsknechte. Lotto moved to the site on 22 June and completed the work by summer 1524, assisted by his pupil Francesco Bonetti. In the 19th century count Gianforte Suardi joined the chapel to the villa with a covered corridor, altering the entrance.

The chapel is dedicated to Saints Barbara and Brigid, whose lives fill the side walls; Barbara's cycle runs past a market scene and a round tower where she is imprisoned. The north wall sets Christ the Vine above the praying commissioners Battista, Orsolina and Paolina, with the Latin line "Ego sum vitis vos palmites" in gilded letters.

The chapel sits inside the Suardi villa park in Trescore Balneario, on the old road through Val Cavallina between Bergamo and Lake Iseo. A covered corridor built by Count Gianforte Suardi in the 19th century links villa and chapel; entering that way, visitors meet the south wall before the north wall with Christ the Vine.

At both ends of the vine on the north wall, harvesters with ladders and billhooks try to cut Christ's branches and fall into the void. They stand for heretics, not craftsmen, and some carry their names in inscriptions drawn from historical figures.
