Lenin's notorious name has returned to a public spot in Eastern Europe: the Gdansk shipyard where Lech Walesa led his anti-communist movement. Though just for a film set, the move has sparked emotions.

A reconstructed sign with the words "In the name of Lenin" returned to the shipyard on the Baltic coast late Sunday. Mayor Pawel Adamowicz allowed the sign to go up to help create a historically accurate backdrop as the Oscar-winning director Andrzej Wajda makes a film about Walesa.

Solidarity, a labor union that is heir to Walesa's freedom movement, and Law and Justice, a conservative party, protested strongly Monday. Law and Justice asked prosecutors to investigate whether Adamowicz broke a law against propagating communism.

Prosecutors say there is no crime since the reconstruction is for educational purposes.
