The story behind the castle
One woman's obsession with getting every detail right.
Astolat began as a two-year plan mostly held in one person's head, then took twelve more years, a network of specialist artisans, and a small fortune in gold leaf and stained glass to become the castle it is today.

Meet the maker
Elaine Diehl, a miniaturist based in Colorado, spent two years planning Astolat before construction ever began, holding most of the design in her head rather than on paper. What followed was twelve more years of building, from 1974 to 1987, with goldsmiths, glass blowers, silversmiths, and carpenters brought in from around the world to furnish it to her standard.
Once finished, Astolat went on display in Diehl's own museum shop in Sedona, Arizona, where it became a popular stop for visitors until her retirement in 1996, the same year the castle found its next owners.

Why "Astolat"
The castle takes its name from a tragic figure in Arthurian legend, and the choice was no accident.
Elaine of Astolat is the heroine of Alfred, Lord Tennyson's poem "The Lady of Shalott," a young woman who dies of unrequited love for Sir Lancelot after leaving her tower for one glimpse of him in the outside world. Tennyson's telling turned her into one of the more haunting figures of Victorian poetry: beautiful, isolated, and ultimately undone by her own longing.
It's a fitting namesake for a castle built for no one to live in, a structure made purely to be admired, down to the smallest hinge and windowpane.
“Out flew the web and floated wide; the mirror crack'd from side to side; 'The curse is come upon me,' cried the Lady of Shalott.”
— Alfred, Lord Tennyson, "The Lady of Shalott" (1832)
From workshop to museum
Astolat's story didn't end when construction did; it has changed hands, homes, and audiences in the decades since.
