I can see the VC Mansion in the second map. But what intrigues me are not only the other buildings in the upper map#3 but the rather large ponds or lakes shown in the middle of today’s Parade ground in map #3 . You can see Turtle Brook coming down between Vault and present day Broadway but these ponds are new to me. I am wondering if these building are not only houses, out buildings and barns but perhaps also used to store Ice? There is a rather long structure that looks like a half bracket or a capital E going east and west below the buildings and ponds and north of the Mansion.
