The Guild Chapel in Stratford-upon-Avon was established by the Guild of the Holy Cross. The chapel dates from the 13th century and is famous for its medieval wall paintings. The chapel walls were covered with paintings of saints and bible stories in the 15th century. During the Reformation in the 16th century, such images were banned and often destroyed. The wall paintings of the The Guild Chapel were hidden under layers of paint for centuries. They were rediscovered in the 20th century.
