Discovered in 1998, during an archaeological survey of a construction site, the Miami Circle or the Brickell Point is the only known prehistoric architecture in the US. The site features a perfect circle about 38 feet (11 meters) and 24 mysterious holes carved into the limestone. Research suggests that the site could date back to between 1800 and 2000 years. Often nicknamed the Stonehenge of America, the versions about its origin range from aliens, to native Indians to sewage systems. The Miami Circle was declared a part of the U.S. National Register of Historic Places in 2002 and enlisted as U.S. National Historic Landmark in 2009.
