This structure welcomes visitors to Ponce de Leon Springs, a major tourist attraction near DeLand. The statues of Ponce de Leon and the girl are symbolic of the historic background and glamour of the gardens. Behind them is a bas-relief map of the state.
I was talking about this earlier, but I want to mention in a more visible post that Ponce de Leon Avenue, specifically mentioned in the Japan clue and where the Lost Waddles flyer was found in Atlanta, connects to major road Spring Street a few minutes away from the shrine. Also, popular hangout Ponce City Market is located nearby on the site of the Ponce de LeonSprings and is an entrance to the green space/hiking trail known as the BeltLine, where there are probably lots of places to tie keys to tree roots and dig for buried treasure
