Opening of the Museum of the History of Polish Jews in Warsaw

Nearly two decades in the making, the more than $100 million institution officially opens to the public this week amid a month of high-profile, state-sponsored events marking the 70th anniversary of the Warsaw Ghetto Uprising.

“It’s incredible, incredible, incredible how things have changed,” Sliwinski told JTA. “I remember commemorations of the ghetto uprising under communism when only a few people showed up. How good it was that we were optimistic.”

Sliwinski organized Jewish cemetery cleanups and other pro-Jewish initiatives under communism, when Jewish practice and culture were suppressed by the regime.

In 1995, then-Foreign Minister Wladyslaw Bartoszewski, an Auschwitz survivor, appointed him post-Communist Poland’s first official ambassador to the Jewish Diaspora, part of the state’s unprecedented outreach policy.

On Sunday, both Sliwinski, now 73, and Bartoszewski, 91, joined hundreds of local Jews and other VIPs as Poland’s chief rabbi, Michael Schudrich, unveiled a mezuzah at the museum’s main entrance.
