The map collection contains over a million sheets of maps, charts and plans as well as thousands of atlases.

This is the largest map collection in Wales, and one of the largest in the British Isles.

The collection contains a wide range of materials from the latest electronic mapping to 16th century maps and charts on vellum.

The collection specialises in Welsh material; but also has a large number of items covering the rest of the world.

More detailed information on individual aspects can be found on the map collection page.
