A Medieval-Style Castle in the Heart of Florida

In the historic coastal city of St. Augustine, Florida, where centuries-old architecture meets the Atlantic breeze, stands a mysterious and majestic structure: Castle Otttis. This spiritual and artistic landmark resembles a medieval Irish fortress and captivates visitors with its timeless design and sacred atmosphere.

Castle Otttis—intentionally spelled with three “t”s—is not a relic from ancient Europe but a modern creation rooted in history and faith. Built in the late 1980s by artist Ottis Sadler and a dedicated team, the castle was inspired by 1,000-year-old Irish abbeys. It was conceived not as a home or tourist site, but as a landscape sculpture that honors early Christian architecture.

Inspired by Celtic Monastic Tradition

The structure pays homage to the Celtic monks of Ireland, who lived in solitude yet built sacred spaces that fostered spiritual community. Castle Otttis draws from that monastic spirit—its appearance is rugged and fortress-like, but its purpose is peaceful and reflective. It’s a one-of-a-kind Irish-style castle in Florida, merging faith, art, and historical inspiration.

A Sacred Interior Experience

Inside Castle Otttis, visitors encounter a space designed for spiritual reflection. The interior resembles an early Christian church, with hand-carved wooden pews, high stone arches, and subdued natural lighting. There is no electricity or modern technology—just silence and reverence. The thick stone walls create a sanctuary-like stillness, shielding visitors from the outside world.

Though it looks like a fortress, Castle Otttis is a spiritual monument, not a defensive structure or tourist attraction. Its builders dedicated it “to the glory of Jesus Christ.” Today, it serves as a venue for non-denominational services, private prayer, small weddings, and occasional educational events. It’s a place of meaning rather than entertainment.

A Hidden Gem Near St. Augustine’s Historic District

Castle Otttis is located just north of the historic center of St. Augustine, not far from the Mission Nombre de Dios—the site of the first Catholic Mass in the continental U.S. This proximity enhances its symbolic importance and makes it part of a broader story of spiritual heritage in St. Augustine.

Because of its sacred purpose, Castle Otttis is not open for daily public tours. Visits are usually by appointment only, ensuring that the castle remains a quiet, respectful space. Its limited access adds to its mystery and sense of authenticity.

A Unique Castle Experience in the U.S.

Unlike commercialized attractions, Castle Otttis offers visitors a rare and profound experience. It’s not about crowds or photo ops—it’s about peace, history, and a connection to something greater than ourselves. Many who visit say it’s one of the most unexpected and moving places in St. Augustine.

Whether seen as an art installation, a spiritual retreat, or a medieval-style structure, Castle Otttis defies simple categorization. It reflects ancient inspiration but carries a timeless message of reflection, reverence, and faith.
