The Royal Opera House has cancelled the remaining shows in its season, which had been due to run until late July.
The Covent Garden venue confirmed that performances, events and activities would not resume during its current season, which is scheduled to end on July 23.
All theatres in the West End are remaining closed until at least May 31.
The opera house confirmed that in addition to events in its buildings, all tours, school events and cinema screenings are also cancelled for the same time frame.
"We will keep any date for re-opening under constant review following direct guidance from the government and Public Health England," a statement said.
It added: "We want to take this opportunity to thank our community of artists, craftspeople and other backstage staff, as well as our supporters and audiences, as we continue to navigate through this incredibly difficult time.
"Although our building is closed, we remain open 24/7 online through our #OurHouseToYourHouse programme, which provides a suite of content that audiences can access for free anywhere, anytime. Our Create and Learn programme also provides free home-learning opportunities for children and young people between now and 17 July, with new activities, challenges and courses added every Friday."
