Constructed in 1832, the Belknap Mill is
the oldest unaltered brick textile mill in the United
States. Once a hosiery mill, it houses an intact hydraulic
power plant and a bell cast by George Holbrook, apprentice
to Paul Revere. The Busiel Mill, built in 1853 as a hosiery
mill, was later used for the manufacture of clocks, electronic
relays, and organs. The Belknap-Sulloway
Mill and the Busiel-Seeburg Mill were individually listed
on the National Historic Register in 1971.
Marker location: Located by City
Hall, on Beacon Street, off Business Route 3.
