The Wing House Museum in Coldwater

The roof gives it away. On Marshall Street, just north of downtown Coldwater, stands a tall, ornate house topped with a steep, curving metal roof that looks like a hat pulled down over the upper floor. That curved roofline is a mansard, the signature of the Second Empire style — the showy Victorian fashion that wanted a house to announce, before you reached the door, that the people inside had done well.

Newlyweds Jay and Frances Chandler built it in 1875. They did not keep it long: in 1882 they sold to Lucius Wing, a local bank president, and after that the house became a Wing family affair for three generations. That long single tenancy is partly why so much of the place survived intact rather than getting gutted and modernized by a string of owners.

In 1974 the Branch County Historical Society took the house on and turned it into a museum, and the National Register of Historic Places added it the next year, in 1975. The rooms are furnished to the period — not a stage set built to look old, but a real 1870s home left standing and dressed the way a comfortable family of the era actually lived, down through the parlor and the bedrooms.

What gets you is the ordinariness of it once you are inside: somebody’s banister, somebody’s good front room, kept up not by a state agency but by neighbors who volunteer the hours. The mansard roof is the brag from the street. The real thing is the quiet upkeep that has held a single house in place for a century and a half.
