The four-pillared canopy seen at a Jewish wedding ceremony is known as a Chuppah.

The chuppah is open on all four sides, like Abraham and Sarah's tent.

During the wedding ceremony, the couple stands beneath the structure which represents the home they’ll make, their future marriage bed, and protection from God.

Chuppah designs and styles vary.

In Hindu religion this structure is known as a Mandap.
