Will by which padre João Soares de Albergaria established a chapel, entailing to it all his properties in Alter do Chão. He designated his brother, Sebastião Galvão, to administrate it, declaring that, after his death, he had to be succeeded by his eldest son or daughter. If Sebastião died without leaving legitimate descendants, the chapel would be administrated by Luís Galvão Pegado and his successors. The future chapel's administrators were obligated to support the celebration of 2 perpetual daily masses for the institutor's soul in the main church of Avis, where his body would be buried, next to his wife's remains. Followed by an approval deed issued on 1669-07-30.
