Greece's Culture Ministry had a conference poster showing a Nazi flag over the Acropolis replaced after it drew sharp criticism, with Culture Minister Lina Mendoni telling lawmakers organizers were wrong to choose it.
Zoe Konstantopoulou, leader of the opposition party Course of Freedom, raised the issue in the parliamentary committee on cultural affairs.
Mrs. Mendoni said she learned of the poster after a protest from the National Council for the Claim of Germany's Debts to Greece, which called the image provocative and asked the ministry to withdraw its patronage of the conference on the German occupation.
"They were wrong to choose it," she said.
The poster was then withdrawn and replaced.
Mrs. Mendoni said the image is a historical photograph from the archive of the German Historical Museum, not made for the event.
The picture carries heavy symbolism in Greece. German forces raised a swastika flag over the Acropolis after taking Athens in April 1941.
In May 1941, two young Greeks, Manolis Glezos and Apostolos Santas, tore it down, an act of resistance that became a national emblem.
The row touches a live dispute.
Successive Greek governments and groups such as the National Council have pressed Germany for reparations for the occupation, which Berlin says was settled legally.
The ministry did not say who organized the conference or whether it keeps its patronage.
