Although the building is almost the same it always was, the organisation of the Estates Theatre has changed several times in its history. In 1798 it was called the Estates Theatre when it was bought by the Czech Estates. When the Provisional Theatre opened in 1862 the Estates Theatre started to put on German plays and the name was changed to the Royal Provincial German Theatre. From 1920 and 1948 it got its name (Estates Theatre) back again. In 1948 the organization became part of the National Theatre and was called Tyl Theatre (after dramatist J.K. Tyl). In 1990, after some restoration, it became known again as the Estates Theatre.
