A kingdom awaits! Three East Tennessee castles you can visit or rent

Williamswood Castle in South Knoxville, Tennessee on Thursday, January 17, 2019. The home, modeled after a medieval castle, was built by Julia Tucker beginning in 1991 and took six years to complete. Many of the items in the home were sourced from around the Knoxville area. The castle is listed on Airbnb.
In the right settings, East Tennessee can feel reminiscent of medieval Europe. You can see knights fight at Schulz Brau Brewing, roam ancient forests in the Great Smoky Mountains and try your hand at archery on the campus of Ancient Lore Village.
You can even explore castles.
While their history might not date all the way back to the middle ages, each of these castles has its own fascinating story, down to their dungeons and up to their towers.
See how they came to be and how you can pay them a visit for a taste of what royalty feels like in Tennessee.
Greenback Castle
This palace is more of a prayer house.
Floyd "Junior" Banks Jr. built Greenback Castle by hand starting in 1994 and dedicated his elaborate creation to God.
Also known as Fortress of Faith and the House of the Almighty, it features religious text and imagery throughout, with messages such as "Satan has almost owned this place twice" and "Jesus is King."
The eclectic structure, made of materials including brick, glass and cinderblock, is adorned not with thrones and scepters, but with Banks' curious carvings, mosaics and pictographs.
Anyone is able to go to the Fortress of Faith, which is about 30 miles outside of Knoxville in Loudon County. Banks − described by one Yelp reviewer as a "fascinating gentleman with some really interesting stories" − is known for showing visitors around and chatting with them about the property.
Banks said in 2022 that around 10,000 people come to see the castle each year.
Location: 250 Lee Shirley Road, Maryville
How to see it: It's free to visit the castle, but donations are appreciated. It's open 7 a.m.-8 p.m. daily.
Millennium Manor Castle
One castle in East Tennessee wasn't built to withstand armies. It was built to in case of the apocalypse.
Between 1937 and 1946, William Andrew Nicholson and his wife, Fair Nicholson, built the structure in hopes of surviving Armageddon, which the couple thought would happen in 1969, and the 1,000 years to follow, according to the Historical Marker Database. However, Fair died in 1950 and William in 1965.
Today the castle is owned by Dean and Karen Fontaine. It's fortress-esque, with a surrounding wall and battlements that look as if they might serve as a blockade for oncoming enemy forces − or the end of the world.
Location: 500 N. Wright Road, Alcoa
How to see it: Once it opens for the season April 4, tours will be available noon-5 p.m. Saturdays and Sundays. Guided tours are $15, with a maximum of $40 for up to eight people.
Williamswood Castle
Williamswood in South Knoxville tells one family's story of grief and love. Today, anyone can stay in the Scottish hunting lodge-style castle.
The structure was created in the early 1990s by Julia Tucker after her son, Bill Powell, died of complications caused by AIDS in 1991. Powell was a young historic preservationist who loved the family's Scottish heritage. Before his death, he urged his mother to buy the property where Williamswood now sits from the Tanasi Girl Scout Council in 1985.
Tucker designed and built the stately fortress to honor her son.
Williamswood is now an Airbnb where visitors can admire Tucker's creative touches, such as a trap door, solarium, tavern and even a secret passageway. The interior is full of dark wood trim and stained glass and decorated in a way that transports you straight to the past, with pieces such as a suit of knight's armor and coats of arms.
