The webinar series Strongholds of the World will present non-European fortresses and fortified towns from around the world.

This series is a cooperation between Aarhus University research programme "Materials, Culture and Heritage" and the Marburg Working Group for European Castle Research.

Dr. Doo Won Cho presents Namhansanseong, a fortified town built since the 12th century on several hills close to Seoul that has been used as a stronghold until the 20th century. About 30 min presentation is followed by a discussion.

The session was recorded and is available to watch at YouTube.
