The name Mercer Street is first mentioned in the Survey of Birmingham of 1553. This was a result of the prominence of the area in the cloth trade. In the 16th century and 17th century, Mercer Street rapidly developed and became cramped. In the early 18th century Mercer Street was known as Spicer Street, reflecting the growing grocery and meat trade that had begun to take over from the cloth trade. By the end of the century the street was known as Spiceal Street. Despite being overcrowded and cramped, many houses on the street had gardens as indicated by an advertisement for a residential property in 1798. Houses were constructed close to St Martin's Church, eventually encircling it. These became known as the Roundabout Houses.
