About

Weddings

Castleton is one of the only waterfront wedding venues in southern New Hampshire. Our breathtaking scenery and private setting overlooking the picturesque waters of Cobbetts Pond in Windham, NH creates a unique wedding opportunity.

Corporate & Special Events

Castleton Banquet and Conference Center is an excellent choice for corporate seminars. It’s a multi-functional building that provides you with the privacy that you need for your corporate event. Castleton is perfect for a one-day off-site training where your company can build in a little fun along with its business.

Flexibility

With the ability to host inside in one of our adaptable halls with multiple room size options, or outside in the garden or at the beach, you have a few choices as your event plans progress.

The Food

From allergies and restrictions to vegan and vegetarian options, we believe that serving food that accommodates each of your guests is extremely crucial. No one at your event will feel left out!

The People

The beauty of Castleton can only be matched by the incredible service. We understand that  events require experienced staff to create a truly special experience.
