The site has plans for a movie theatre, retail, restaurants and hotel, but archaeologists are delaying those plans. Along with a Tequesta village, the site also served as a Army fort, plantation and Henry Flagler's Royal Palm Hotel, which was built in 1897.
In March, preservationists and the developers agreed to a compromise, which would preserve some of the ancient Tequesta circles and have them enclosed in glass for visitors and tourists.
According to the New York Times, archaeologist Dr. William Pestle filed a lawsuit against the agreed deal, which could delay development of the site even further.
