In 1063 a smith named Ibragim ibn Osman made the famous Ganja Gate be the order of a Seddadid Dynasty ruler. It is a masterpiece of craftsmanship of that time. The gate made of cast iron was decorated with stamped ornaments and patterns from the outer side. The ornament contained the name of the master in kufi language and the date the gate completion.

In 1139 year a Georgian tsar Demeter I thanks to the earthquake, which had practically destroyed the city, attacked Ganja and captured the gate as his trophy. The gate weighing a few tons was carried by the survived citizens of Ganja on their backs.

Only one half of the gate has survived. It is built in the wall of Kelatin Monastery across from the Georgian king David IV tomb.
