Thornewood Castle Lakewood

Nestled on four acres at American Lake and dotted with old growth fir trees is Thornewood Castle. Built in 1908 by Chester A. Thorne, this 27,000 square foot manor is of the Gothic Tudor style and is the only one of its kind on the west coast. Built as a single family residence, Thornewood is now a gracious country inn that has been lovingly restored.

Thornewood Castle is both an indoor and outdoor destination wedding venue right here in the Pacific Northwest. Weddings and receptions at Thornewood Castle can take place outdoors in our sunken English garden, inside in the Great Hall and Ballroom, or out on the grounds for a wedding overlooking the lake.
