Cathedrals in the High Gothic style became increasingly elaborate. Over several centuries, builders added towers, pinnacles, and hundreds of sculptures.
In addition to religious figures, many Gothic cathedrals are heavily ornamented with strange, leering creatures. These gargoyles are not merely decorative. Originally, the sculptures were waterspouts to protect the foundation from rain. Since most people in Medieval days could not read, the carvings took on the important role of illustrating lessons from the from the scriptures.
In the late 1700s, architects decided that gargoyles and other lavish sculptures were tasteless. Notre Dame Cathedral in Paris and many other Gothic buildings were stripped of their ornaments. The gargoyles were restored to their perches during a careful restoration in the 1800s.
