Digital Strategy & Cataloguing
Located in Mayfair, London, Altea Gallery is a trusted dealer in original rare antique maps, atlases, and globes. Authenticity guaranteed.

Our Story. Where It All Began

In 1995, Altea Gallery was at the forefront of the digital revolution in the antiquarian map trade, becoming one of the first dealers to launch a fully illustrated online catalogue. This innovation allowed us to expand our reach beyond traditional boundaries, offering collectors from around the world access to our carefully curated selection.

Today, we continue to maintain both a distinguished physical gallery in London’s Mayfair and a robust online presence, blending the best of both worlds to serve a global clientele.

  • The National Library of Singapore
  • David Rumsey Map Collection

  • British Library
  • National Library of Wales
  • Stanford University
  • State library of Florida
  • Staatsbibliothek zu Berlin
