4 Fire House is located in Oshkosh, Wisconsin.

[2] The fire house was designed by William Waters and built in 1868, after major fires in 1859 and 1866.

By the time it closed in 1946, #4 spanned the transitions from volunteer firemen to professionals, from mobile pumps to hose wagons, and from horses to motorized trucks.

[3] Later, the building housed a sign company for a time.

It was added to the State Register of Historic Places in 1995 and to the National Register of Historic Places the following year.
