Mermaids and Fountains

I have always loved the four metal, maybe copper mermaids in the grassy area in front of the Municipal Palace. A couple of years ago one of them disappeared. Tuesday she was replaced with an exact copy, except in CEMENT. What a shock!!! At least she has been replaced.

We think they were once fountains, along with the fuente del soul, the dolphins on la ropa and likely other things. So what happened? Did electricity and water become too expensive to keep them running? Was it the personal project of one of our past presidentes? There are bound to be even more that we aren't aware of and would llke to look at...
