Miami Circle, Archaeological site in Brickell, Miami, US.

Miami Circle is an archaeological site in Brickell, Miami, where traces of a pre-Columbian settlement are preserved in the limestone bedrock. The site is now maintained as a small park with panels explaining the shape and meaning of the carvings protected below the surface.

In 1998 developer Michael Baumann demolished an apartment complex at 401 Brickell Avenue to build a condominium. A salvage excavation led by Bob Carr and John Ricisak revealed 24 holes cut into oolitic limestone, forming a 38-foot circle. Radiocarbon dating of burnt wood placed it between 1,800 and 2,000 years old. Florida bought the 2.5-acre site for $26.7 million in November 1999; it was listed on the National Register in 2002 and named a National Historic Landmark in 2009.

The holes in the limestone mark what was likely a structure built by the Tequesta, a people who lived along Biscayne Bay long before European contact. The circle suggests that this spot held special meaning for the early inhabitants of South Florida, either as a gathering place or ceremonial center.

The park is located on Brickell Avenue in downtown Miami and is freely accessible. The site itself remains covered for protection, but the panels on display give an overview of the excavations and what was found beneath.

The circle was found only because a routine archaeological survey was pressed on developer Michael Baumann before construction. Surveyor Ted Riggs calculated the centre from a few visible holes and predicted where the rest would lie; excavation then exposed all 24. The state paid $26.7 million in 1999 and reburied the limestone rather than display it.
