Blacksmiths recreate Viking-era anchor using historical techniques in Denmark

Students and instructors from the UK’s National School of Blacksmithing are participating in an experimental archaeology program at Aggersborg, a Viking-era circular fort in northern Denmark. The team is using historical methods and bloomery iron to recreate a Viking-age anchor.

The reconstruction process is guided by X-ray analysis of early medieval anchors, which allowed researchers to identify weld lines and various layers of iron. By using manual bellows and historical fuels, the blacksmiths aim to understand how Viking craftsmen adapted their techniques when steel was scarce.

The completed anchor is intended for a reconstructed early medieval workboat inspired by the Gislinge vessel. The project seeks to highlight the craftsmanship and technical expertise that enabled Viking maritime travel, trade, and exploration across Europe.
