Alinja Castle, known as the 'Machu Picchu of Azerbaijan,' is perched majestically on the peak of a rocky mountain in the Nakhchivan Autonomous Republic. This medieval fortress, dating back to the 7th century, carries a rich historical significance and has been a strategic military center for various empires, including the Seljuq and Atabegs. The castle was renowned for its impregnability, earning the nickname 'Albanian Machu Picchu' due to its inaccessibility and stunning location. It is believed that Alinja Castle served as the treasury and stronghold for the Atabeg state, guarding their wealth and secrets. The journey to the castle is a challenging hike that rewards visitors with breathtaking panoramic views of the surrounding landscape. Over the centuries, the castle has undergone several restorations, preserving its historical architecture. Its ruins, including the remnants of walls, gates, and the inner keep, invite travelers to step back in time and explore the rich history of the Silk Road and the region's ancient civilizations.
