Rudolph Grotto Gardens and Wonder Cave is one of Wisconsin’s most unusual religious and folk-art attractions, covering more than five acres behind St. Philip the Apostle Church in Rudolph, Wisconsin. The sprawling garden is filled with winding paths, rock formations, bridges, flowers, trees, shrines, statues, memorials and chapels, all created as part of Father Philip J. Wagner’s decades-long effort to build a place of devotion. Wagner began developing the grounds in 1919 after promising the Virgin Mary he would build a shrine if his health improved following a serious illness while studying for the priesthood in Europe. The first shrine, modeled after the grotto at Lourdes, was completed in 1928 with help from Edmund Rybicki, who became Wagner’s lifelong collaborator. Thousands of tons of rock gathered from local farms were eventually incorporated into the landscape.
The centerpiece is the Wonder Cave, a completely man-made underground passage built inside a towering formation of rock and concrete. The cave extends for one-fifth of a mile and contains 26 shrines, with its design inspired by the catacombs of Rome. Inside, visitors encounter religious scenes, statues and hand-crafted plaques in a narrow, winding passage that changes in height and direction. Many of the statues and plaques were carved from Carrara marble in Italy, while shells, colored glass, tile and other materials were incorporated into the grotto’s elaborate surfaces. The Rudolph Grotto Gardens remain open year-round, while the Wonder Cave, museum, chapel and gift shop operate seasonally. There is no admission charge for the gardens, although the Wonder Cave has a small fee.
