Historic Maps of Portsmouth
Portsmouth is one of the most mapped places in Britain. Below is a selection of historic map images that can be found online. Note that some early maps show planned defences rather than structures actually built. For detailed descriptions of early maps of Portsmouth see Hodson, D. (1978).

In October 2020 the British Library released 17,000 images of maps and views from George III’s Topographical Collection (K.Top) on the image-sharing site Flickr Commons. You can search for specific items via Explore. Add ‘George III’ to your search term in order to bring up only maps and views in the K.Top collection. When you have found the record for the item you require, select ‘I Want this’ and then look for 'Digitised item Go', which will take you to the relevant image(s) on Flickr.
An additional 32,000 images were released in July 2021, comprising George III’s collection of atlases and albums of views, plans, diagrams, reports and surveys, produced between 1550 and 1820. You can view the full collection on Flickr by visiting the Topographical collection of King George III.
