WISCASSET — A nonprofit history organization is hosting a behind-the-scenes tour of Castle Tucker from 10-11:30 a.m. on Saturday, Aug. 11.

The Behind Closed Doors Tour of the historic mansion takes people to places not usually seen when visiting the 201-year-old house. The home is filled with original furnishings and some of the decoration from the family that lived at the house for more than 140 years. The tour includes visits to rooms and stories not included on a general tour.

Admission is $10 for members of Historic New England and $15 for nonmembers. Advance registration and payment is required and space is limited.

Castle Tucker was built in 1807 by one of Wiscasset’s most prominent citizens, Congressman and Judge Silas Lee. In 1858, Richard Tucker Jr., a captain and scion of a prominent Wiscasset shipping family, bought the house for his new and growing family.

The Tuckers updated and redecorated the home to reflect the fashions and styles of their time, much of it in a style popularized by one of America’s earliest lifestyle connoisseurs, Andrew Jackson Downing. Very little was changed in the house after 1900, including a kitchen with four generations of kitchen technology still in place.
