There is a long story behind this pool.
Hemingway bought the original property for $8000 for back taxes owed.
There used to be boxing ring in the back yard and he trained young boxers. His wife didn't like it and told him they should put in a swimming pool. he was not in agreement.
Not long after that he went off to Paris to stay for a while and do some writing. When he returned the pool was in at a cost of $ 20,000, which was all the money he had.
They had no filtering system so the water had to be changed weekly. It was not a great idea.
