The school continued in the 1600s buildings on its original site, until it was relocated in 1882. The school was relocated in the current Main School Building which dates from 1765 and had at different times housed a foundling hospital and the Shrewsbury workhouse, before translating to this current use. In order to meet this new purpose, it was remodelled by Sir Arthur Blomfield (whose other educational commissions include and Marlborough College and Lady Margaret Hall, Oxford). At this time, the original premises were converted to a public Free Library and Museum by the Shrewsbury Borough Council, opening in their new role in 1885; over the course of the 20th century the library purpose gradually took over the whole building, to which major restoration was done in 1983.
