D.C.’s first and oldest synagogue is also almost certainly its most nomadic.

The original home of Adas Israel is about to make its second move in as many years, and its third over the course of its storied history. This final trek, slated for January 9, will put the building in position to be the cornerstone of a brand new museum slated to open in 2021—the Capital Jewish Museum.

The first synagogue in the District was built in 1876 at 6th and G streets NW, near what is now Capital One Arena. It was inaugurated by no less than the sitting U.S. president at the time, Ulysses S. Grant. But by 1908, its congregation outgrew the 25-by-60 foot building and they headed a few blocks away to 6th and I (in 1951, the congregation moved to its current home in Cleveland Park). Over the ensuing years, the original synagogue building served a number of other purposes before being threatened with demolition to pave the way for Metro’s headquarters.

The Jewish Historical Society of Greater Washington fought to save it, and in 1969, they moved the building three blocks away over the course of a dramatic, three-hour trek.

It spent the next few decades stationary as the Lillian & Albert Small Jewish Museum, a small historic site and home for the Jewish Historical Society of Greater Washington.

But, in recent years, with redevelopment again threatening the building’s livelihood—this time in the form of the enormous Capitol Crossing project, which is constructing three new city blocks over I-395—the group’s leaders found themselves turning to the same playbook: Pick up the 273-ton structure and move it. In November of 2016, movers hoisted the structure onto a special truck bed and pulled it 60 feet away.

Now, they’re gearing up to move it to its last home. On a Wednesday morning next month, specialty movers will roll the building down 3rd Street NW to rest, finally, a block away. There, it will eventually a key part of a much larger new museum, which will feature gallery space, classrooms, archives, offices, and a green roof space.

“[The new Capital Jewish Museum] will be a center of Jewish life and culture and will tell some of the stories that we haven’t been able to tell,” Wendy Turman, deputy director of the Jewish Historical Society, told DCist in 2016. “Our historic synagogue will the be the largest artifact in our collection and really the centerpiece, the sort of jewel in the crown of the new museum.”

After the Adas Israel building is in position, construction will begin on the rest of the modern new museum facility.

Executive director Kara Blond explains in a video about the project that when the museum finally opens, visitors will “come up the front steps, enter between the historic synagogue and the new museum—literally between the past and the future.”

The synagogue’s move will take place beginning at 9 a.m. on January 9, 2019.
