The William Brown Library and Museum is a Grade II* listed building situated on the historic William Brown Street in Liverpool, England. The building currently houses part of the World Museum Liverpool and Liverpool Central Library. Following on from the then-recently completed St. George's Hall across the street, the new building was designed by Thomas Allom in a classical style including Corinthian columns and was modified by the Liverpool Corporation architect John Weightman. The new building opened its doors in 1860 with 400,000 people attending the opening ceremony.
