John G. Cullmann was a German immigrant who conceived the idea of a German colony and proceeded to buy a tract of land in 1872. The first 5 German families arrived by train and within that first year grew to 30 families. The town was so successful that it became the seat of the Alabama legislature after 6 years.
One of Cullman's notable
attractions is the Clarkson Covered Bridge, built in 1904 and one of the largest in Alabama. The surrounding area was designated a historic site in memory of the Battle of Hog Mountain in 1863. A picnic area, hiking trails and a non-operating gristmill can be enjoyed by visitors.
