Where is the well located in Browns Folly?

Been looking at pics of well with ladder over the top and was wondering where it was located with reference to the map.

It's marked on the map as "WELL". There's not a huge number of features marked so it's a little curious as to why you can't locate it on the map?

Maybe the wrong map - other post says they can't find the entrance...
