Louis was also known for his charity, saying, “The peace and blessings of the kingdom come to us through the poor.” He fed the beggars at his table and ate their leftovers. He washed their feet and healed the wounds of the lepers. Every day, he fed over 100 poor and needy people.
Louis was responsible for the creation of many great architectural wonders, including the Sainte Chappelle, which he commissioned as a reliquary of the crown of thorns. He was patron of the Collège de la Sorbonne and founded many hospitals and homes for the poor.
On August 25, 1270, Saint-Louis died of the plague. He is the patron of masons and builders.
