The sinkhole gardens are a remnant of some magnificent sunken gardens of the late 19th century situated in the Mt Gambier region of South Australia.
The sinkhole was once a typical limestone cave, formed by the corrosion of limestone rocks by seawater waves. When the roof of the cave collapsed it naturally created a sinkhole.
The first glimpse of the sunken garden is from the descending staircase with platforms on each terrace. At the base of the sinkhole is a fountain and the area has been planted with hardy hydrangeas, palm trees and tree-ferns.
Day Twenty-one of the 2019 A-Z Challenge which I am participating in during the month of April. The challenge is to post six days a week, Sunday respite or catching up with other participants and their posts. Each of the twenty-six days represents a letter of the alphabet and while each post stands alone they form part of a loose theme reflecting our retirement trip around Australia.
