## History

Ownership of Newkirk's Indies Inn changed in 1983 when the Pompano Beach Barrington Group purchased the holdings and made extensive changes. The nine-hole par 3 course designed by Robert Trent Jones was removed to make room for a resort expansion approved in 1986. The resort name was changed to Hawk's Cay Resort and Marina. Additional swimming pools and recreational facilities were added in the late 1990s.
The Singh Company of Key West, well known for the Truman Annex, entered the Upper Keys in the middle 1990s and began Hawk's Cay Village. This added several hundred Caribbean-style cottages all with water views, porches and the traditional white picket fence.
There are presently 381 homes, multiple recreational facilities and complete convention facilities.
