Westwood firefighters have knocked down a three-alarm fire that tore through a nearly 200-year-old Westwood home early this morning, officials said.

The Westwood Fire Department got a call for the fire at 355 Dover Road just after 5 a.m., said Fire Captain Robert Valluzzi. Firefighters from neighboring towns including Walpole, Norwood, Dedham, Medfield, and Dover assisted Westwood’s response.

Just before 8 a.m., companies on scene are engaged in extensive overhaul, putting out hot spots, Valluzzi said.

The two-story, single-family home was built in 1830, and is worth just shy of $1 million, according to town assessor records.

No further information was immediately available.
