Plaistow Carhouse

The Plaistow Carhouse is a historic trolley barn at 27 Elm Street in Plaistow, New Hampshire. Built in 1901, this brick structure now houses Plaistow's fire and police services. It was used by the relatively short-lived trolley service between Plaistow and adjacent Haverhill, Massachusetts, which operated until 1930. It was thereafter used as a storage facility by an amusement company, and was purchased by the town in 1979.

The building was listed on the National Register of Historic Places in 1980.
