Lori Castle, also known as Lori Berd, is an 11th-century medieval fortress founded by David Anhoghin, positioned between the Dzoraget and Miskhana rivers near Stepanavan in Armenia's Lori Province. Rising nearly 1,500 meters above sea level on a rocky plateau, the fortress once served as the capital of the Kyurikyan Kingdom and housed approximately 10,000 residents during its 11th to 13th-century peak, functioning as a vital trade hub connecting Ani, Dvin, and Tbilisi. The 214-meter-long defensive wall encircles remains of a palace, bathhouses, chapels, and private apartments, providing archaeological evidence of its importance as both a military and administrative center. Though damaged by Mongol forces in 1236, the fortress was rebuilt and continued to play a significant role under Georgian, Turkish, and Persian rule.
