The Borgarvirki Fortress (Northwest Iceland)

The Borgarvirki Fortress in North West Iceland

The Algarian Stronghold or the Algar Stronghold or The Stronghold was a vast man-made mountain-like structure serving as the de facto capital of Algaria. It is a mountain-like heap of rocks. During the calving season, they hold a contest for hauling rock and the Stronghold had been there for several thousand years.

Silk observed that Algars are nomads and the Stronghold's purpose was to give Murgo raiders something to attack.

Inside the Stronghold was a maze of walls.

Kal Torak tried to lay siege to it for 8 years (4867-4875) before he gave up in disgust and moved to Vo Mimbre.
