He'll stay jailed until afterward, court police said.
The magistrate and a prosecutor will collectively decide afterwards whether he is going to be held in prison or released pending his trial.
Lignadis, 56, resigned on Feb. 6 as the artistic manager of Greece's National Theater amid reports of the alleged behaviour.
Charges of violent behaviour, sexual harassment and rape against many well-known Greek celebrities, directors and officials have proliferated in the last month, developing a #MeToo second in Greece.
Greece's culture ministry, Lina Mendoni, said Friday she had requested a Supreme Court prosecutor to investigate rates of harassment and rape at the theater community. The opposition has accused her of attempting to protect Lignadis, who was appointed in 2019 by the present conservative government.
