Bathtub Madonna

These shrines most often house a statue of the Blessed Virgin Mary but sometimes hold the image of another Catholic saint or of the Sacred Heart.

While often constructed by upending an old bathtub and burying one end, similar designs have been factory produced.

These factory produced enclosures sometimes have decorative features that their recycled counterparts lack, such as fluting reminiscent of a scallop shell.

The grotto is sometimes embellished with brickwork or stonework, and framed with flowerbeds or other ornamental flora.

Somerville, Massachusetts, a city which has traditionally had sizable Italian, Irish, Portuguese and (more recently) Brazilian populations, has over 350 Catholic yard shrines in a town of about four square miles, with more than 40 in actual bathtubs.
