Indoor or Outdoor Destination Wedding Venue


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. Be sure to check out our Wedding Photo Gallery to see the options available!

We can accommodate guests indoors or outdoors. If you are planning an outdoor wedding in the Seattle/Tacoma area, you should consider having a contingency plan for unexpected rain or overcast weather.

Our most common wedding event is the combined ceremony and reception, but we can accommodate just the ceremony and/or just the reception. Your wedding will be a very important and special day in your life, and we will customize your event to your wishes.

Indoor Weddings in the Great Hall

Make your grand entrance down our 500 year old solid oak staircase into the Great Hall as your fiance waits in front of our sandstone fireplace or 16th century stained glass windows. Ornate Victorian sculpted high ceilings, paneled walls, hardwood floors and original artwork create an intimate and romantic setting to say "I do". Even if an indoor ceremony is your "Plan B" our Great Hall is a stunning option sure to wow your guests.

There is something truly romantic about a waterfront ceremony. The castle is nestled right on American Lake giving you the option to say your "I do's" overlooking the water. Evening ceremonies may even be able to capture the sky changing color as the sun sets on the opposite side of the lake.

Indoor receptions in the ballroom

Our Ballroom is perfect for your intimate indoor reception. Seating up to 125 guests surrounded by antique furniture, artwork and a beautiful chandelier. A mixture of grand 8 foot  and round tables allows for a personalized and unique dining experience. 



Many brides find that minimal or no additional decorations are needed at Thornewood Castle, though you are of course free to have additional decorations if you wish. We can discuss these details with you further.

We just want your wedding to be as beautiful, special and stress-free as possible!

Outdoor Garden wedding Ceremony

Enjoy the beauty of the Pacific Northwest by tying the knot in our "Secret" Sunken English Garden surrounded by flowers, sculptures, antique brick walls and fountain. Our white chairs are a beautiful contrast to the immaculate green grass. Stand on top of our staircase with trees and a wall of hydrangeas in the background or face the castle and let your guests marvel at the architecture.  Either way additional decorations are not really needed.


Gorgeous Wedding Photos

Couples who wed at Thornewood will have opportunities for amazing wedding photos with the castle and the grounds as a backdrop. The dressing suite, the stairs, the gardens, the fountains and sculptures, the brick, the architecture, the fireplace, the windows, the lakeside...the options for timeless wedding photographs are endless.

Outdoor receptions on the lawn

American Lake creates the perfect backdrop for your outdoor reception. A wonderful breeze coming off the lake helps to keep guests comfortable even during warm summer months. With the sun setting on the opposite side of the lake, sunset  is truly stunning. 


Get the best of both worlds by having your reception on our Loggia. This large covered patio allows you to enjoy the beauty of our grounds while also having protection from the sun or rain. Seat 50 guests under the loggia, use it for cocktail hour or set up your buffet. Beautiful and functional space.
