ATHENS (AFP) ― Greece is preparing a case for the return of antiquities looted by the Nazis during World War II, officials said on Friday.

“The entirety of the archaeological service’s archives is under investigation” in a search for photographs and sketches of lost items, the general secretariat for culture said in a statement.

“Final and scientifically documented conclusions on the issue of Greek cultural treasures looted during the (Nazi) occupation will be drawn in the coming months,” the secretariat said.

The search will also cover Byzantine and post-Byzantine relics whose destruction or seizure had not been properly examined until now.

The culture secretariat added that tens of thousands of Neolithic shards illegally taken out of Greece during the 1941-1944 occupation are to be repatriated from Germany.

“The repatriation procedures are being completed,” it said.

The Nazi occupation period still weighs heavy on Greeks and continues to color the perception of Germany.

Further tension is caused by Berlin’s insistence on an austerity-heavy economic programin Greece for the past three years in return for EU-IMF rescue loans.

Greece has said in recent years that it reserves the right to claim wartime reparations from Germany, saying it was forced to accept unfavorable terms during negotiations in the 1950s.

In April, the Greek finance ministry completed a search of state archives to determine the level of outstanding reparations for Nazi war crimes.

But its report has been classified as secret and has been forwarded to the foreign ministry and the Greek state’s legal counsel for further handling.

According to reports, Greece has estimated the outstanding sum at 162 billion euros ($210 billion).

Germany, which has fronted a large share of the eurozone rescue for Greece, rejects the idea of paying any further reparations.

In September, the German government reiterated that it has already paid “substantial sums” to Greece as part of bilateral agreements on war reparations.
