The owner of the house where Adolf Hitler was born is fighting the Austrian government’s right to take possession of the property.
The interior ministry had been renting the three-storey hours near the German border since 1972 but it has remained empty in recent year because of disputes.
The owner, a retired woman, filed a legal challenge on Thursday.
Her lawyer, Gerhard Lebitsch, told reporters she had refused offers that were too low from the state.
“The offers regarding the purchasing price were half-hearted,” said Lebitsch. “At best it was the sale value of a regular house. There were never any serious talks. Always everything got blocked.”
The Austrian government doesn’t want Hitler’s birth home to be used as a pilgrim site by neo-Nazis and other groups.
The former German chancellor provoked a global war that cost more than 50 million lives.
A decision by the court is expected within the next two weeks.
