Chateau Fairmount
A stone house on Belvidere Hill in Lowell, Massachusetts. Built in 1883, a rest home for half a century, foreclosed in 2009, and bought and restored from 2011 — and open to the neighborhood on Halloween night. A private home the rest of the year.

The modern name of an old house
Chateau Fairmount is what its present owner calls the Arthur Bonney Estate: a Chateauesque stone mansion built in 1883 for the Lowell machinist and inventor Abel T. Atherton[C-001, C-002, C-006], and for nearly half a century the Battles Home[C-023].
The 1981 state survey called it the earliest of Lowell’s major late-nineteenth-century stone mansions and the most elaborate example of its style in the city: rock-faced ashlar, cross gables, tall chimneys, a round tower, a porte-cochère, stained-glass transoms and carved sandstone panels, with oak and Minton tile inside[C-006, C-007].
The house is privately owned, lived in, and still being restored. This site keeps to what the records show, and says so where they fall silent.

Halloween at the castle
On Halloween night the drive is lit by twenty-two hand-built candelabras and the neighborhood comes up the hill for two hours of torchlight, fog, music and treats[C-044].

A note from the owner
People stop at the end of the driveway to take pictures, and when they see me they ask about the house. This site is my answer. I have tried to keep the history to what can be documented, and to label the legends as legends.
If you lived here, worked here, or visited the Battles Home, I would be glad to hear from you — and if you have an old photograph, even more so.
