Tabernacles in Christian churches having multiple compartments or niches, usually two or three, each of which can be revealed or brought forward using a rotating device. The compartments typically could hold a monstrance, a ciborium, and a crucifix; the niches could be highly decorated. Rotating tabernacles were considered mechanical marvels, and were relatively rare, most common in 18th-century northern European Roman Catholic churches.
