At the top of the right side of the transept is the chapel of the Carneiro family, founded by João Carneiro, Master of the Escola da Sé de Braga. This chapel is the work of the architect Diogo de Castilho and was completed in 1500, as can be seen the inscription on the plaque on the left side wall. The ribbed vault adorned with flower shapes, covers this chapel. In the altarpiece there is a painting painted in the third quarter of the 16th century representing the baptism of Our Lord, with the blessing of the Eternal Father and an unidentified figure, supposedly the donor of the painting.
