I cannot give you any information, except to say- Freemasonry is legal in Cuba, and there are many lodges. Apparently, the government there does not care about Masonry. I have read that Women's Masonry "co-masonry" operates there as well.
I suggest that you check with the secretary of your lodge. He will have a listing of all of the operating lodges in Cuba.
If you are able to attend any lodges there, I would like to hear your report.
I attended a lodge in Moscow, Russia (Phoenix #17) back in October of 2006.
