About Us
The Armstrong family’s Castleton Banquet & Conference Center
sits proudly overlooking popular and well known Cobbetts Pond in Windham,
NH. The pond is named after the town’s first minister dating back
to 1722. Until 1986 the properties were formally occupied as a public
bathing beach known as Armstrong and Duncans Beaches.
The Armstrong portion of the property has been held by various family members
for seven generations. In 1972, George Armstrong purchased the five acre
Duncan Beach site and combined the two beaches, which were occupied as
such until 1986. At that time, it was the only privately owned public
bathing beach in the state of New Hampshire.
In 1987 and 1988, Castleton was constructed and proudly opened its doors
on September 14, 1988. Since opening we have been hosting wedding celebrations,
ceremonies on site, baby and bridal showers, Birthday parties for all
ages, Silver and Golden anniversaries, trade shows, seminars, Proms and
many holiday parties.
