MARQUETTE, IA (WKBT/AP) -

No one was injured  after a fire tore through a historic Iowa river town.

It happened in Marquette, which is just across the Mississippi River from Prairie du Chien.

The Marquette fire chief says at least one business and three residences were damaged or destroyed by the fire.

The business was Marquette Hardware which was housed in a 100 year old all-wood building.

The cause is still under investigation.
