“Tomorrow 21st July 1935 will see another landmark in the history of Ramsgate. It is the official opening of the Marina Bathing Pool and Cafes by His Worship the Mayor Alderman Dye.”
This image shows the Pool during construction. It was taken July 1st 1935 and it was opened 20 days later!

This is one theory. The other theory goes back to its construction. Taken from Michael's Thanetonline
"Some say the problem was the old design of the building and that thee
pool was actually on 'stilts' and you could walk underneath it at low

below began to erode, and as a result the foundations moved, causing the
pool to crack. This was patched for years until repairs were
impossible. It was also too expensive to replace."
