I tried the place on our map because I was driving up north anyway but the Hacienda would be the opposite way
Obviously if you have already tried and "moved on" then you wouldn't go back - but the Hacienda Benoit is only 8.3 kms by road in a generally eastern direction from the current "blue spot".
I note that the blue dot has been located close to the "Carretera Jacagua" and presume that was why it was chosen by whoever tried to determine the coordinates for us (not me!!). About 2.5kms away along this road is the "Rio Jacagua". It might seem probable that the ruins would be along the river but I have found a web site for a community group which is trying to improve the condition of the Rio Jacagua and it describes a walk along the river without ANY mention of the ruins! (The Hacienda Benoit is a bit further West still and not really "alongside" the Rio Jacagua) I have sent them an e-mail to see if they can help!
Also the northern dot for Primeros Ingenios Coloniales Azucareros de América is pointing at a baseball field.
3 of the 4 "dots" for this T List site are slightly off. In fact the "Ancient Big House of Palavé" is only 2.6 kms away from the Baseball field!! Whoever chose the coordinates obviously homed in on the word "Palavé"! The southern 2 spots are in fact meant to be the 2 southern sugar mills you mention but one of them (the one at the "Playita") is misplacedELS
- here are my suggested coordinates and titles for the "Primeros Ingenios Coloniales Azucareros de América"
(currently all 4 locations have the same name which is a bit unhelpful!). All 4 sites/buildings are identified precisely on Google Maps and I have checked them using "Satellite view".
Boca De Nigua Sugar Mill 18.372823, -70.060158
The Ancient Big House of Palavé 18.479918, -70.047354
The Ancient Diego Caballero Sugar Mill 18.366534, -70.060232
The Sugar Mill of Engombe 18.448440, -70.001029
