Seaside: From Sanatorium to State Park

Along the misty ocean shores of Waterford, Connecticut, sits an almost forgotten relic of healthcare history. While from the main road, you might only notice a small brown sign marked, ‘Seaside,’ the path beside the sign will lead you somewhere truly unique.

Seaside Sanatorium, a complex of buildings sprawling across the scenic shoreline, spent many years as a tuberculosis hospital. Today, it’s known to the public as Seaside State Park.

As a state park, Seaside Sanatorium has served as the backdrop of many casual walks and scenic photoshoots.

But, some say the old buildings dotting the property haven’t forgotten their past. From eerie voices to shifting shadow figures, there is no shortage of ghost stories around Seaside Sanatorium.

Although not immediately open to the public, many investigators have visited the old sanatorium


In the early 1900s, tuberculosis was a major health crisis. While sanatoriums to treat the disease were common across America, doctors in Connecticut hoped to build one just for children. A small facility opened in an old hotel in 1918, but demand soon outgrew it.

With help of architect Cass Gilbert and Connecticut’s Tuberculosis Commission, a new, larger hospital took shape on Connecticut’s shore. The new facility opened in Waterford in 1934.

For a while, Seaside Sanatorium served its purpose well. Medicine of the era claimed the sunshine and ocean air in the area would help soothe symptoms. While sun and ocean air weren’t true cures, modern medicine soon came to the rescue. By the early 1950s, science had advanced to the point that tuberculosis had become treatable.

In no time, large treatment centers like Seaside Sanatorium became unnecessary. The sanatorium closed in 1958, but reopened soon after as a geriatric center, and then a care center for the mentally challenged.

Several more decades went by, with Seaside Sanatorium staying afloat as a mental hospital. Over these years, there were conflicting reports of the quality of care. Rumors spread about rampant, violent abuse taking place through the 1970s.

However, these are often thought to be nothing more than rumors. Regardless, treatment came to an end in 1996, when the facility closed for good. After that, the complex sat empty and forgotten for many years.

After almost two decades of emptiness, signs of life came back to the old hospital. In 2014, the governor of Connecticut designated it as Seaside State Park, and it opened to the public shortly after. While the buildings are not accessible, the grounds are open to the public.

Ever since opening as a park, the site has seen renewed interest and countless visitors. Some who walk the park even say they’ve spotted a few ghosts lingering with them.
