I am particularly interested in old maps from the Lake Champlain Region, as I researched its history when it was part of New France. It has led me to search for maps of the region.
In my quest, I recently discovered this map in a Wikipedia article. It is a map part of a collection from the Boston Public Library. It is a fascinating and pretty unique military map, as it includes the dates of the battles during 1777 Burgoyne’s campaign right on the map at various locations.
And if you are interested in old maps as I am, you may want to check the site of the Library of Congress. For example, here are the search results on “Lake Champlain maps” on this site. And if you are in Washington DC, don’t miss the chance to see them in person. Trust me; you won’t regret it!
