About & Contact
Bexhill-OSM is part of a community of mappers that want to create a free, editable map of the world. You can learn about the global project at the official OpenStreetMap website.
This independent website looks to continuously archive Bexhill as it stands today; heralding history, community and business in an informative, accessible form.
-Although Bexhill-OSM is not a business directory as such, nor a place for direct advertising, we do welcome listings on all publicly visitable places.
-Web-development and the underlying map data are maintained by Alexis Markwick. I hope you enjoy using it as much as I do creating it.
