Jomsborg
Jomsborg (Jómsborg) is a semi-legendary Viking fortress and harbour on the southern Baltic coast, known from Norse sagas and medieval chronicles as the base of the Jomsvikings. Its exact historical location is uncertain and debated; some identifications place it at or near present-day Wolin in Poland. Medieval sources describe it as a fortified harbour with a stone tower on an arch guarding the entrance.

As it stood in 1000
What Jomsborg looked like in its prime.
A compact coastal stronghold at the waterline: a stone tower mounted above an arched harbour mouth, the arch spanned by masonry and fitted with an iron gate; catapult gear sits on the tower platform. A sheltered basin holds beaked Viking longships tied side by side. Behind the harbour the fort's clustered timber-and-stone buildings rise only a little above the shoreline, the whole silhouette low, heavily functional, and focused on the quay and defended entrance.
