Grodno, Belarus ? When the spring melt began, the people living on New Street made a horrific discovery: Mixed in with dirt from a construction site that had been dumped in front of their homes were human jawbones, femurs and even entire skulls.

The bones are the remnants of a once vibrant Jewish community that was nearly wiped out in World War II. Its memory had been buried even deeper in 1963 when officials in this then-Soviet republic built a soccer stadium over a Jewish cemetery dating back to the 18th century and containing the graves of Jews who died during the Nazi occupation.

“My grandmother was buried in the cemetery, and the Soviet authorities never warned us that they would start constructing a stadium there and that we could move the bodies,” said Grigory Khasid, 78, the oldest of the 1,600 Jews now living in Grodno.

There was no warning this time, either. Construction workers began renovating the Nieman stadium in January, carting off truckloads of soil to fill in holes on New Street and other nearby dirt roads over the next two months.

As the winter’s snow melted, broken headstones with Hebrew engravings were found mixed in the dirt along with bones and gold teeth. People have swept bones to the side of the road, and some have tried reburying remains in the streets.

But with each rain these relics of the past wash up again, leaving some people squeamish.

“Everyone knows these are bones from the Jewish cemetery at the stadium,” said Galina Pilits, a medical lab worker who lives on New Street. She said people in the neighborhood hoped street crews would pave over the bones.

The city’s Jewish community, which numbered more than 20,000 before the war, wants the remains reburied with respect. Khasid has collected headstones and taken them to Grodno’s sole surviving Jewish cemetery.

City authorities ordered workers to collect bones found at the stadium for reburial. Occasionally they send municipal workers to collect bones from the streets, said Sergei Dubavets, a city council member.

“But who is going to walk along and pick up individual bones on the streets? It’s impossible to collect every bone,” said Mikhail Korzh, president of the Council of Jewish Organizations of Grodno.
