The city of New Baltimore is a waterfront community that has evolved
from an early manufacturing and shipping community to one with resort
ships bringing tourists to visit world-class hotels, as well as being
the epicenter of an interurban railroad system between Port Huron and
Detroit and, in modern times, a friendly waterfront community. The area
post office was established in 1851 and called Ashleyville for founder
Alfred Ashley. In 1867, New Baltimore officially became a village, and
it soon prospered and grew. The village became a city in 1931 and
annexed land from St. Clair County, which meant leaving the governing
authority of Chesterfield Township.
