Albarracín — The Secret of the Independent Taifa and its Eternal Medieval Heritage.
In 965 AD, when the Umayyad Caliphate crumbled, the Berber dynasty of Banu Razin seized the rose-pink cliffs of Albarracín and declared themselves sovereigns of a taifa kingdom. For three centuries, they resisted Christian siege and conquest through cunning diplomacy and impenetrable mountain fortifications. But legend whispers of a hidden pact—a secret accord written in cipher and sealed within the city's oldest stones—that guaranteed their survival when all other taifas fell. The accord was never found. Now, standing within the labyrinth of medieval ramparts, narrow streets, and ancient towers, you must decode the symbols left behind by Mardanis ibn Baldaj and his successors. Each monument holds a clue. Each riddle unlocks a fragment of the truth. Can you reconstruct the lost treaty before the final sunset, or will the Banu Razin's greatest secret remain buried forever in the shadow of the Guadalaviar?

« Whoever possesses Albarracín holds the key to Aragon. »— Aragonese popular proverb
The Red Rock and its Moorish Lords
In the 11th century, after the collapse of the Caliphate of Córdoba, Albarracín emerged as an independent Taifa under the Berber dynasty of the Banu Razin. Despite its modest size, this fortified city, perched on a rocky spur surrounded by the Guadalaviar River, became a strategic bastion. Its unique position and the sagacity of its emirs allowed it to successfully navigate between the powerful Christian kingdoms to the north and the Muslim dynasties of Al-Andalus, creating a singular cultural and political enclave.
For almost two centuries, the Taifa of Albarracín maintained remarkable autonomy. Its history is marked by fluctuating alliances, secret treaties, and impressive defensive architecture, whose red walls are today its emblem. In 1170, it was ceded by the Banu Razin to Pedro Ruiz de Azagra, a Navarrese nobleman, marking the end of the Muslim era and the beginning of a new Christian lordship, but the spirit of its foundation endures in every alley and every stone of this 'frozen medieval time'.
