Pardon the ramblings of an old man - I'm organizing old charts and logs for my daughter and future generations and found an old chart we have from the south china sea. A marked mine field off the southern coast of a Vietnamese island (Hon Tranh).
In a similar vein. Annotation on currentcharts here: "FORMER MINED AREA - The approaches to Port Moresby have been swept and are open to surface navigation only. They are not safe for anchoring, trawling, bottoming of submarines or seabed activites"
In N Brittany too, the chart mentions former mined areas.
When Navionics scanned the French paper charts of S Brittany, they failed to notice that a small text did not refer to the name of a place but to the tide: "marée semi-diurne" means "semi-diurnal tide". This isn't a village.
