The Castillo de San Marcos National Monument in St. Augustine, Florida, has made history. It’s the first U.S. national park to earn the Certified Autism Center™ (CAC) designation.
The park was awarded this important designation by the International Board of Credentialing and Continuing Education Standards (IBCCES). This achievement underscores the park’s dedication to creating an inclusive environment for autistic and sensory-sensitive visitors. It also hopes to pave the way for a more accessible national park system.
This milestone is part of a broader initiative for the city of St. Augustine. The St. Johns County Chamber of Commerce is working to make the area a Certified Autism Destination™. This means that not only the park but also nearby hotels, restaurants, and attractions are focused on meeting the needs of sensory-sensitive individuals and their families.
The history

The Castillo de San Marcos is a monument steeped in history. Constructed between 1672 and 1695 by the Spanish, this coquina stone fortress is the oldest masonry fort in the continental United States. Originally built to defend Spain’s claim in the New World, the Castillo has withstood sieges, changes in power, and the test of time.
Visitors can explore the fort, walk along the towering walls, and imagine life as a soldier stationed here centuries ago. Guided tours and living history demonstrations bring the fort’s past to life and offers an immersive experience for both history buffs and casual visitors.
What to expect
In addition to its historical significance, the Castillo de San Marcos offers plenty for visitors to enjoy. The sensory guides introduced as part of the CAC designation provide valuable insights into the sights, sounds, smells, and textures visitors can expect during their visit. This includes:
- The booming sounds of historic cannon firings;
- The gritty texture of coquina walls;
- The salty sea breeze rolling in from the Matanzas Bay.
These sensory guides, combined with staff training and thoughtful accommodations, ensure that everyone can experience the fort’s grandeur in a way that suits their needs.
Why it matters
The Certified Autism Center designation is a significant step for Castillo de San Marcos for several reasons:
- Fosters inclusion: It ensures that visitors with autism and sensory sensitivities can fully engage with and enjoy the park.
- Impacts the community: This initiative aligns with St. Augustine’s broader commitment to accessibility, enhancing the area’s appeal as a welcoming destination for all.
- Sets a precedent: As the first national park to achieve this certification, Castillo de San Marcos serves as a model for other parks across the country.
- Expands accessibility: By implementing sensory guides and staff training, the park is creating a more equitable space that honors its mission to serve all visitors.
A step forward
The Certified Autism Center designation not only highlights the park’s dedication to inclusivity but also reflects a growing movement toward making public spaces accessible to everyone. For families with autistic or sensory-sensitive members, this achievement offers the promise of memorable visits to one of the nation’s most iconic historical landmarks.
Whether you’re drawn to its rich history or stunning waterfront views, or have an autistic family member, Castillo de San Marcos National Monument is now better equipped than ever to welcome everyone.
