In 1842, the Michigan Central Railroad bypassed the original village and built a depot 1.5 miles (2.4 km) to the west when an offer of $1.50 an acre was offered (compared to $2.00 an acre at the previous city center) [1].

The historic Romanesque Whistle Stop Depot offers displays of local interest and is available for rental.

[5][6] The Grass Lake Historical Society also operates the Coe House Museum.

The home was constructed in 1871 for Henry Van Winkle, who owned and operated a hardware store and farm equipment dealership in Grass Lake.

[7] According to the United States Census Bureau, the village has a total area of 0.94 square miles (2.43 km2), all land.

[8] According to the 2010 census,[10] there were 1,173 people, 462 households, and 306 families residing in Grass Lake.

In 1937 this episcopate, headed by Bishop Policarp Morusca, established a cultural center in Grass Lake.

John Radzilowski, the author of an entry on Romanians in The American Midwest: An Interpretive Encyclopedia, wrote that this center "remains the most significant Romanian cultural institution" in the United States.
