There is a major historic site in Miami, called the Miami Circle. It is one of the oldest indigenous sites in South Florida, discovered during construction excavations. It is a circle marked with holes that once held 24 poles, suggestive of a clock, and it was found in association with many artifacts attributed to the Tequesta / Tekesta people who once inhabited this region of South Florida. Due to its highly urban location and the controversy surrounding whether it would be preserved as a historic site or built over as part of the property that encompassed it, the circle itself has been left underground and marked with informative placards. I’ve never stood at this site, but I have been on Miami River tours that went past it. Its riverfront location makes it obvious, as the only spot for miles where the buildings don’t edge directly onto the shore, even with the circle itself underground.
