Gulf Marine State Park on Point Cadet in Biloxi, Mississippi, most likely taken in the late 1960s through the early 1980s. While I can't date it precisely from the image alone, the architecture, landscaping, and absence of later development suggest it predates the casino era and Hurricane Katrina.
Here's what makes this site historically significant:
A unique waterfront state park
Gulf Marine State Park occupied one of the most scenic locations on the Mississippi Gulf Coast, where Biloxi Bay meets the Mississippi Sound at Point Cadet. The park was designed to celebrate Mississippi's coastal environment and marine heritage, offering visitors:
An aquarium and marine exhibits (at various times)
Educational displays about Gulf wildlife
Fishing and boating access
Picnic areas
Observation decks overlooking the water
Meeting and event facilities
The octagonal buildings in your photograph were a distinctive part of the park's design.
What you're seeing
Several features in the photo help identify the location:
The wooden boardwalk leading to the entrance.
Two matching octagonal buildings flanking the entrance.
The larger central building overlooking the water.
A long pier and seawall extending into Biloxi Bay.
The open water beyond, with Deer Island lying across the Sound (not easily visible because of distance and haze).
