I did a screenshot tour of the old Port Royal:
Governor's Mansion, the "far" entrance
Governor's Mansion, the near entrance, with guard shack
Backed down the hill to the shipwright
Swam out from the shipwright looking back for perspective. Gov's mansion on far right, up hill
In that last shot you see shops. Here was the best one:
The inside was never finished. Pirates used to meet up in here. It was also fun for PR hide-and-seek.
Behind the town, but not through a "portal" was the graveyard. You can see a "portal" to the right and the back of the main town's buildings to the left.
Heading back out to the front of the town, there were vendor stalls in the open. You can see the dock in the background, to the right.
Looking back towards town from the dock. See the three buildings on the left? Either the middle one, or the one on the right was Will Turner's place. Slightly to the right of middle the harbor ran into a little stream. There was a little rock bridge over it.
On the rock bridge looking back toward the main town
Left as you look at these, past those 3 freestanding buildings, was another bridge that led up the hill to Fort Charles.
This is my limit for images. I've only got a couple more of the hill and Fort Charles itself, but hopefully this gives the people who never got to see it a better feel for old PR.
