Ave Maria Grotto, in Cullman, Alabama, United States, is a landscaped, 4-acre (16,000 m2) park in an old quarry on the grounds of St. Bernard Abbey, providing a garden setting for 125 miniature reproductions of some of the most famous religious structures of the world.

[1][2] The stone and concrete models are the work of Brother Joseph Zoettl, a Benedictine monk of St. Bernard Abbey, who devoted some 50 years to the project, the last three decades (1932 to 1961) almost without interruption.

They incorporate discarded building supplies, bricks, marbles, tiles, pipes, sea shells, plastic animals, costume jewellery, toilet bowl floats and cold cream jars.

Also displayed are a number of secular buildings and the occasional pagan temple, including the Alamo Mission in San Antonio, the Leaning Tower of Pisa, Spanish missions, German castles, South African shrines, Hansel and Gretel's Temple of the Fairies, and even the St. Bernard Abbey power station, where the monk worked shoveling coal.

A central artificial cave constitutes the Ave Maria Grotto proper, with pretend-stalactite-encrusted ceiling and statues of the Virgin Mary and assorted monks and nuns.
