General information

Our mapping system allows you search for a place name and to view the selected place in various maps so you can see how it has changed over the years.

It is also linked to the 1901 Census, Griffiths Valuation (1855/56) and the Tourist Surveys from the 1940s (to be added soon) so you can plot holdings and population changes as well as get descriptions of places from the past.
