The Chapel of São Pedro de Balsemão sits in a quiet rural setting about five kilometres south-east of Lamego, accessible by a small country road through walnut groves. The exterior is plain and easy to mistake for a farm building. Inside, the small nave and side aisles reveal carved capitals, an early-medieval roof structure and a striking 14th-century episcopal tomb.
The chapel is open only at restricted hours (typically mid-morning to early afternoon, closed Mondays) and is staffed by a caretaker who explains the building in Portuguese. A worthwhile half-hour for anyone interested in the deeper layers of Iberian church history.
