All the missions had bells. There is a complete list of the 21 missions, by location on our website.
The mission bells were hung in a bell tower or companario, or in some missions in a bell wall. They were used to notify the inhabitants of church services (the day started with the ringing of bells), to announce daily events (meals, for example) and to signal the arrival of visitors. The bells were rung extensively on feast days as part of the festivities.
