In 2017, members of the Cobourg Museum Foundation undertook to create a map of Cobourg as it would have been in 1867.  But it was not just a paper map but a 3D model.  It was on display for a short while in the lobby of Victoria Hall - below is a photo of it taken at that time.  It is planned to feature it from time to time at the Sifton-Cooke Heritage centre which is operated by the Museum Foundation.
