Greenback Castle Is East Tennessee Folk Art You Can Walk Through

A wall of red brick can turn into an archway lined with old bottles. A cluster of glass marbles may catch the eye from the masonry. Then a corridor bends toward another open-air room, another handmade tower, another small corner that seems to have appeared simply because Floyd “Junior” Banks had an idea and a little more material to use.

Greenback Castle, also called the Fortress of Faith, is not a polished historic house with ropes, display labels and a prescribed route. It is a sprawling, deeply personal folk-art structure built by hand over decades, beginning in the 1990s, and it rewards the sort of visit where you slow down and keep looking.

Banks built without conventional blueprints, and the place has the lively, accumulating character that suggests. Towers, walls, archways, passages and open-air rooms join one another in a layout that is less about symmetry than discovery.

The materials are a large part of the story. Discarded red bricks, concrete scraps, tiles, scrap metal, seashells, bottles and bits of glass all become building blocks or decoration. Instead of hiding the reused materials, the castle puts them forward.

Some walls invite close inspection. Marbles and found objects are set into the surfaces, while bottle-lined arches give a familiar discarded item a new job as ornament. The construction is both masonry and assemblage art, with each section carrying its own collection of textures.

The castle has a maze-like quality. A walk through it brings unexpected landings, turns, nooks and crannies, with rooms that do not follow a standard floor plan and corridors that keep the eye moving ahead.

That irregularity is the pleasure. One area may be mostly brick and concrete; another may pull attention toward embedded glass, carvings or painted detail. The site is large enough that a person can keep finding new surfaces instead of taking in the whole project in a single glance.

Not every space has the enclosed feeling implied by the word castle. Several areas are open to the air, turning the structure into a sequence of outdoor rooms as much as a building. It is an unusual setting for a leisurely walk: part handmade fortress, part sculpture garden, part puzzle assembled at full scale.

The Fortress of Faith name is not a decorative afterthought. Banks’s Christian faith shapes the site through religious and spiritual imagery, carvings, murals and personal artistic statements worked into the structure.

Hand-painted murals add color against the heavier brick and concrete. Intricate carvings provide another reason to pause, particularly for visitors who enjoy looking at the labor in folk art as much as the finished overall effect.

The result is not a conventional attraction built around a theme. It is a singular builder’s long-running vision, with faith, salvage and persistence all visible in the same wall.

Banks sometimes greets visitors himself. When he is available, he may talk about the castle’s history, the materials gathered for it and the spiritual purpose behind the work.

He may also lead people through rooms or around sides of the structure that are easy to miss during an independent wander. A conversation with the builder can give useful context to a place that intentionally resists the tidy logic of a formal museum.

Still, meeting Banks is not something to count on. The castle works as a self-guided stop as well, with enough detail in the walls, passages and outdoor spaces to occupy an unhurried visit.

The castle stands among mature trees in a wooded setting that includes pecan trees. The setting softens the hard surfaces of brick, tile and concrete and gives the property the quiet feel of a roadside discovery that has wandered well beyond the roadside.

Several short trails lead away from the main structure through the woods. A cleared side trail adds another walk through the property, with wildflowers appearing along the way at times.

There is also a maze and other art installations to explore, along with a pet cemetery. These smaller features fit the spirit of the property: the visit keeps extending into one more handmade or personal detail.

The approach comes off a paved road onto a small dirt road serving several homes before reaching the castle. That arrival helps set expectations: this is an informal folk-art site, not a large commercial complex with a visitor center and a scripted itinerary.

Admission is free, and a donation box is available for people who want to support the project. Visits are generally made during daylight hours, when the masonry details, outdoor rooms and trails are easiest to explore.

The ground includes uneven surfaces, corridors, outdoor areas and wooded paths. Sturdy shoes make sense here, and posted safety instructions matter, particularly around elevated spots and unfinished sections. Access can vary within the ongoing structure.

Greenback Castle suits an unhurried Sunday drive or a day trip built around something genuinely uncommon. Give it time for the little discoveries: a marble in a wall, a painted panel, a surprising arch, a turn that leads somewhere you did not expect.
