Listed in the National Register of Historic Places, the Trade and Commerce Building in Superior was built in 1890 by railroad owner Henry D. Minot. It later housed the city's offices and is thus often refered to as "Old City Hall". The architectural style is refered to as Richardson Romanesque. The architect was Clarence H. Johnston of St. Paul. The structure is built out of sandstone blocks from the Kettle River quarry near Sandstone, MN.
In 2015, the building is home to the Red Mug Coffeehouse, the Spirit Room (run by the building's current owner, Jeff Heller) and a number of other businesses.
