That is the Sand Castle. Not sure how long it was open, one of my captains was employed there many years ago.
Me and a friend to a walk thru this property back in 2013 while I was still living up there.
Everything had been completely stripped out from the plumbing, to the wiring, to the flooring.
Was full of Haitian squatters at the time along with what appeared to be drug consumption
dens. Believe it or not there was a few security guards at the front entrance however
they paid no mind to all of the traffic coming in and out. I was told by someone a long time ago
it was a functioning resort until it was hit by a hurricane but aside from one conversation, I don't
recall anyone ever speaking about a hurricane slamming Sosua in the 1990s?
