As part of the Connecticut Trust for Historic Preservation’s 40th anniversary, it will present a “private access tour” of the Wilton Historical Society on Saturday, Nov. 21, from 11 to 12:30. Guests will have  exclusive access to five historic buildings on the society’s campus at 224 Danbury Road, Wilton.

The one-of-a-kind talk and tour, given by Wilton architect Rob Sanders, will include commentary about the evolution of Wilton’s early architectural styles and a chance to explore the interconnected Betts House (c. 1740), Burt Barn and Fitch House (1772), as well as the 1860 Abbott Barn and blacksmith shop.

Sanders, whose architectural practice has a strong presence in historic preservation, restoration, and renovation, was instrumental in moving the historic buildings to their current location. Open to the public, the event will conclude with a light reception.

The Connecticut Trust for Historic Preservation, in partnership with the 1772 foundation, awarded the Wilton Historical Society a grant of $15,000 for exterior painting of the Betts House, the Burt Barn and the Fitch House in 2014. Jordan Sorensen, membership and events manager, is “thrilled to be able to showcase the Wilton Historical Society’s dedication to the upkeep of their historic buildings and their innovative programming and exhibitions.” The painting project was finished this summer. The special access tour is a way to mark both the Trust’s 40th anniversary and the completion of the project.

Tickets are free, but registration is required as space is limited. Visit http://bit.ly/1PwFWRz to register for this event.

The Connecticut Trust was established in 1975 to provide technical assistance, financial assistance, workshops, publications and advocacy in preservation matters and issues.
