Meet the "eruv," a creative way to mesh ancient religion with today's urban and suburban spaces

We discuss all kinds of transportation challenges here at Greater Greater Washington. But observant Jews face a unique barrier: on the Sabbath and other holy days, they can't drive cars or ride the bus. Symbolic structures called "eruvim" are examples of how a community adapts to the surrounding built environment.

Jewish law prohibits doing "work" during a total of 1,500 hours each year. That includes driving and also carrying many objects outside one's home. However, an eruv (plural "eruvim") creates a symbolic private space, inside which it's religiously permissible to do things like carry house keys and books, push strollers, and walk with canes.

To qualify as an eruv, there needs to be an unbroken boundary surrounding an area, but it can be as thin as a piece of string. They're typically cobbled together along existing buildings, fences, and telephone and power lines.

Eruvim around the Washington region

There are nearly a dozen public eruvim in greater Washington, and many more private ones enclose lots with single- and multi-family residences. Much of DC is inside two eruvim, and eruvim wrap around approximately 40 square miles in Montgomery County. There's also an eruv enclosing the University of Maryland's College Park campus.
