[1] Crystal Spring Farm is located in a rural area of southwestern Brunswick, its building complex set southeast of the junction of Pleasant Hill and Woodside Roads.

The farm complex includes ten buildings, organized roughly in a U shape, with the main house at the eastern end.

These buildings include concrete barns for housing dairy cattle and processing their milk, a Quonset hut for the storage of hay, equipment sheds and workshops, and a silo.

New owners converted it to principally dairy farming in the early 20th century, and in 1941 it was purchased by Maurice Dionne,[3] whose brother Bert, a veterinarian, took over its operation.

[2] In 1997 the Brunswick-Topsham Land Trust (BTLT) purchased 160 acres (since expanded to more than 300), with the aim of preserving the farm as open space and a working agricultural area.
