Crewmen working on a sewer project in Aalborg, northern Denmark, unearthed a 14th century sword on Tuesday. Plumber Jannick Vestergaard and machine operator Henning Nøhr were digging on the west side of Algade, a street in the city’s downtown, when a long blade emerged from the ground. They contacted the Northern Jutland Historical Museum which dispatched archaeologist Kenneth Nielsen to examine the artifact and find site.

It is a double-edged sword with a blade three feet long (93 centimeters) that is still sharp. The entire sword, hilt included, is 44 inches long. Both sides of the blade have a fuller (inaccurately known as a “blood groove”) down the full length which was used to lighten the weight of the sword without weakening it. Indeed, the whole swords weighs just over a kilo (2.2 lbs). The hilt has a circular pommel and a straight cross-bar with a round cross-section. It is of extremely high quality.

This style of sword was in use as early as the 12th century through the early 15th century. Museum archaeologists have been monitoring the municipal sewer excavations, documenting the stratigraphy of Aalborg. The sword was found in a waste layer on top of the street’s oldest paving. Previous findings in that layer date to the 1300s, which is the basis for the preliminary dating of the sword.

Swords like these were enormously prized, the property of the warrior elite and so expensive that only noblemen could afford them. They were not, as a rule, dropped, forgotten and buried on city streets. The few that have been unearthed were found in graves, buried with their owners as emblems of their status as fighters of noble rank. There is a cemetery nearby, but no trace of a grave was discovered at the find site.

The unusual location may be an indication that the sword was lost during a violent encounter and buried under the thick mud of low-lying ground before it could be recovered. There are marks from combat on the blade, and there were certainly plenty of opportunities for battle in the 1300s. During the first half of the century, the city was part of the Germanic province of Holstein and there were numerous clashes between the Danes and Saxons before Denmark’s King Valdemar IV received the province as part of his bride’s dowry when he married Helvig of Schleswig in 1340.

(I can’t help but speculate wildly and irresponsibly based on nothing at all but the wide possible date range that it might have been lost during the chaos wrought by the Black Death, which tradition has it reached Denmark when a ghost ship wrecked on the coast of northern Jutland in 1349. A full complement of rotting corpses failed to deter people from stripping the ship of its valuables and carrying some nasty little Yersinia pestis stowaways onto dry land along with the loot. Aalborg first received trading privileges from Valdemar in 1342 and quickly became a prosperous port city. Algade is but a few blocks away from the narrowest part of the Limfjord which bisects the northernmost tip of Jutland.)

The sword is now in the process of being cleaned and conserved. Once stabilized, it will go on display at the Aalborg Historical Museum on Algade a hop, skip and a jump away from where it was discovered.
