I want to know the answer to the following question:
In what month and year did the Civic Centre municipal office building become a listed building?
All the background I'm provided with is that "Once a home of Waldorf and Nancy Astor, it was given by Lady Astor to the City of Plymouth as an official residence for future Lord Mayors and is also used today for civic hospitality, as lodgings for visiting dignitaries and High Court judges and it is also available to hire for private events.". Is that enough to answer the question?
Answer: no
