The Angelus bell is a catholic prayer bell that reminds the faithful to recite the Angelus at specific times of the day. Besides the Angelus bell, there are other synonyms that refer to this type of bell, such as the Ave bell, Regina Coeli bell, and Sanctus bell. The Ave bell is rung during the Angelus prayer's recital of the Hail Mary, while the Regina Coeli bell is used during Eastertide to call the faithful to recite the Regina Coeli prayer. The Sanctus bell is used during the Canon of the Mass, and a lesser-known synonym for the Angelus bell is the "Three O'Clock Prayer Bell".
