Built in 1916, it is the county's oldest surviving courthouse, and a prominent local example of Colonial Revival architecture.

[2] The Carroll County Court House stands in Ossipee Village, on the south side of Courthouse Square near its junction with Old Route 28 and Browns Ridge Road.

The main facade is three bays wide, with a shallow project central gabled section supported by paired Doric columns.

It was designed by Albert H. Dow, a native of nearby Tuftonboro who worked in Boston, Massachusetts.

It underwent significant interior work in 1960, again to meet demand for more space, particularly for county offices.
