What is a chapel in castles?

A chapel in a castle is a small church or place of worship that is located within the castle grounds. Chapels were common in medieval castles, where they served as a place for the lord and his household to pray and attend religious services. They were also often used as meeting places for important discussions and gatherings. Chapels in castles were typically staffed by a priest or chaplain, who provided religious guidance and performed religious ceremonies for the castle's inhabitants. Many castles also had small cemeteries on their grounds, where the lord and his family members would be buried.
