For over 150 years the Peacock Brewery has occupied a prominent location in the downtown area of Rockford, Illinois. The site is approximately 2.25 acres and consists of two buildings. For 70 years, this was Rockford’s largest brewery, and the building remains an excellent example of a large beer processing, brewing and bottling facility. Jonathan Peacock, a British immigrant, relocated to Rockford in 1849 and began brewing beer in his home. By 1857, Peacock was ready to expand his operations, and constructed a separate brewhouse on the land between Madison and the Rock River. Later purchased by John V. Petriz from Peacock’s sons in 1899, Petriz built a new brewery over the old one. The brewery plant survived prohibition by concentrating on bottling, but ultimately closed as a brewery, after a final time producing beer after Prohibition, in 1945.
