VERNON, Conn. (WTNH) — Crews started demolishing a historic mill destroyed by fire in the Rockville section of Vernon.

Flames engulfed the building located at 114 Brooklyn St. just before 2 a.m. Monday. There was a welding company on the bottom floor, but the building was otherwise vacant.

Town officials said the building was constructed in 1893 and first occupied by the James J. Regan Co., which manufactured textiles.
