I had a look for the statue today, but it seems, it isn't existing anymore. According to this article, it was created exactly 10 years ago: https://cuba-si.org/827/jose-marti-statue-eingeweiht

I found a spot in the park that looks like the one on the picture, but there was no statue. I wrote to the group that initiated the statue and will let you know if I know more about what happened to the statue.
