LODZ, Poland (AP) — The discovery in central Poland of hundreds of objects that were most likely hidden by their Jewish owners during World War II provided a rare and precious find, officials said Wednesday.

Around 400 items, including silver-plated menorahs, hanukkiahs, tableware and daily use items were uncovered in the city of Lodz last month during the renovation of a house and yard.

“Those residents who buried these items did so most likely thinking that they would one day return for them, that they would be able to retrieve them,” Lodz Deputy Mayor Adam Pustelnik said.

“Most likely, these people lost their lives” in the Holocaust, Pustelnik said. “Such stories are truly rare and precious and also are a great lesson for us all.”

The items were packed in a wooden box and wrapped up in newspapers, said Krzysztof Hejmanowski, a building inspector with the Warbud construction company, whose crew came across the stashed trove.

Officials said the recovered objects will be transferred to the city’s Archaeology Museum. Experts think the box was hidden early on in the war.

The address where the objects were found, at 23 Polnocna Street, was located just outside the perimeter of the Litzmannstadt Ghetto. The occupying Nazi Germans established the Jewish quarter in Lodz in February 1940, and until August 1944 and it held about 200,000 Jews from across Europe. Most died there or in concentration camps.

A Municipal Investment Administration official, Małgorzata Loeffler, said the items and their history stir “emotion and deep thought about the fact that we are not alone, that we leave something behind.”
