WISCASSET — The annual open house at Castle Tucker and Nickels-Sortwell House is scheduled for 11 a.m. to 4 p.m. Saturday, June 3. Castle Tucker is at 2 Lee St.,with Nickels-Sortwell House at 121 Main St.

The free event will include guided tours every half hour of the two landmarks. The last tour will leave at 4 p.m.

Built in 1807, Castle Tucker is filled with the original furnishings and decoration of the family who lived there for more than 140 years. Updated and redecorated in 1858 by Capt.Richard Tucker Jr., the mansion is one of the most complete and original Victorian homes in the U.S.

Very little was changed after 1900, including a kitchen with four generations of kitchen technology still in place where it was used.

Nickels-Sortwell House began life in 1807 as the trophy house of shipping magnate Capt. William Nickels. In 1899, the house was purchased by industrialist and former mayor of Cambridge, Massachusetts, Alvin Sortwell, as a summer home for his large and active family.

Sortwell’s wife Gertrude and daughter Frances restored the house, decorating and furnishing it in the Colonial Revival style. The house offers a warm and intimate picture of life in the Gilded Age through the early twentieth century.
