KEWAUNEE, WI (WTAQ) - Three shipwrecks in Lake Michigan have been added to the National Register of Historic Places.
They include the Australasia near Door County, the America near Kewaunee County, and the EMBA in Milwaukee County.
The Australasia was the largest wooden vessel on the Great Lakes when it started on fire in 1896 and sank soon afterward.
Shipbuilders have examined all three wrecks to get lessons on various construction techniques.
The EMBA was a self-unloading barge. Officials say it still provides lessons on how to adapt self-unloading technology to conditions on the Great Lakes.
