Birmingham Assay Office, Grade II listed Victorian building and museum in Birmingham, England
The Birmingham Assay Office is a Victorian building from 1877 built with high ceilings, large windows, and ornamental stonework. It functions as both an active testing laboratory for precious metals and a museum displaying the history of quality assurance.
The office was established in 1773 after Matthew Boulton petitioned Parliament for a testing facility outside London and Chester. It has been certifying thousands of jewelry pieces and metal objects ever since.
The site reflects Birmingham's role as a major jewelry and metalworking hub where quality standards shaped the entire industry. You can see how this work became central to the city's identity and prosperity.
Visitor access typically requires advance booking as tours operate on set schedules. The building features traditional stairs and may have limited wheelchair accessibility, so plan accordingly.
Birmingham's anchor hallmark was decided by a coin toss between representatives from Birmingham and Sheffield in the 18th century. This random choice became the identifying mark that all metal certified here still carries today.
