The 10th International Symposium on Boat and Ship Archaeology was held in Roskilde, Denmark in 2003. The theme of the meeting was -Connected by the Sea-, and was designed to emphasize the role of the sea, seafaring and watercraft as bridges rather than barriers. Maritime archaeology tends to take place within national borders, with a national focus, yet the very premise of seafaring is the desire to travel beyond the horizon to establish contact with other places and cultures. The conference theme was chosen to encourage the maritime archaeological community to think in international terms.
