St Bernard Abbey/ Ave Maria Grotto

Visited St. Bernard Abbey last week and wandered around Ave Maria Grotto.
From Wikipedia: 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
