Much of the County's early population began arriving in the 1820s as the Hamilton and London Road was improved and settlement increased after 1848 when navigation to Brantford was opened and again in 1854 with the arrival of the railway to Brantford. The stone and brick Brant County Courthouse was built on land purchased from the Six Nations in 1852. The structure housed court rooms, county offices, a law library and a gaol. During additions in the 1880s, the Greek Revival style, with Doric columns, was retained.
