Greenback Castle

Greenback Castle stands as one of Maryville's most unusual tourist attractions, drawing curious visitors with its unconventional religious folk art and architecture. This passion project, created by local resident Floyd "Junior," transforms ordinary building materials into an elaborate spiritual statement through hand-built towers, intricate decorative elements, and religious symbolism.

The castle grounds feature multiple structures in various states of weathering, creating an atmospheric backdrop that feels both compelling and slightly eerie. Visitors can explore the exterior spaces at their own pace, discovering unusual architectural details and Floyd's distinctive artistic vision throughout the property. When Floyd is present (which isn't guaranteed), his firsthand accounts of the castle's evolution and spiritual significance add valuable context to the experience.

The site is free to visit and requires no advance booking, though the property shows signs of age and minimal maintenance. Expect uneven walking surfaces and overgrown areas. Photography is generally permitted, making it popular with urban explorers and folk art enthusiasts.

For the best experience, visit during daylight hours and wear sturdy shoes. While some find the atmosphere unsettling, others appreciate it as a unique example of outsider art and personal devotion. The castle's location in Maryville makes it an interesting stop while exploring East Tennessee's roadside attractions.

Note that facilities are limited, and the site may not be suitable for all visitors due to its rustic condition. Despite its deteriorating state, Greenback Castle remains a fascinating testament to one person's singular vision and determination.
