History of W3 site
W3 was built in two phases between 2001-2002, but for many years it was a car park before then. The site used to be St Mary’s Hospital. It opened in 1904 and was the main maternity hospital for Manchester until it relocated to its current site in the 1970s.
Whitworth Street West (where W3 is now located) was originally called Gloucester Street until 1899, when it was renamed following the death of the famous engineer Sir Joseph Whitworth.
