About Castleton
Family-Owned for Generations, the Property at Castleton is 
A Storied Backdrop for Life’s Memorable Moments
From Former Public Beach To Elegant Event Space
Castleton embodies the rich history and its natural lakeside surroundings on the banks of Cobbetts Pond. Since the late 1900’s locals and others from urban areas have visited, seeking to escape the heat of the cities. Dance halls were popular at the turn of the 20th century for people to gather together and listen to music.
We’ve kept with this tradition, creating an intimate space where celebration among family, friends, and coworkers is a top priority.
1972
Privately Owned, Public Bathing Beaches
In 1972, George Armstrong purchased and combined Armstrong and Duncan beaches into what was, at that time, the only privately owned public bathing beach in the state of New Hampshire.
1988
Doors Open at Castleton Banquet & Conference Center
The Armstrong portion of the property has been held by various family members for seven generations, and from 1987-88 Castleton was constructed. We proudly opened our doors September 14, 1988.

Castleton cannot be beat
My husband and I looked at several reception sites before deciding on Castleton, and we are very happy about our decision. For the scenery, location, and value, Castleton cannot be beat.

I cannot begin to explain just how perfect everything went
We had our wedding last night and I cannot begin to explain just how perfect everything went. Everyone in the staff was Great! Stephanie was amazing and helped us plan every detail.
