The term "Friars Den" suggests a place associated with friars, who were members of certain religious orders, such as the Franciscans, Dominicans, or Carmelites, known for their dedication to a life of prayer, poverty, and service. In medieval times, friaries were religious houses where friars lived, worshipped, and conducted their ministries.
"Friars Den" at Scone Palace is likely a reference to the Abbey which was located within the palace grounds that was once associated with friars or religious activity. Such a site could have served as a place of retreat, meditation, or contemplation for members of religious orders, providing them with a quiet and secluded space to pursue their spiritual practices.
