A bell tower is a structure that houses bells, usually found in churches or other religious buildings. The most famous bell tower is the Leaning Tower of Pisa, which is also known as a CAMPANILE (9 letters). Other bell towers are known as belfries (6 letters), which are typically found in town halls and other civic buildings. Bell towers often have SPIRES (5 letters) or steeples (7 letters) on top, and they are used to PEAL (4 letters) or CHIME (5 letters) bells. PEALS (5 letters) are a series of bells rung in sequence, while SPIRES (6 letters) are tall, slender towers.
