A small fragment of the fortress – the fortress wall – is located in the city cent­re near the Khan Garden. The intact wall of the fortress is the remains of the Shiralibay Tower. In the 16th century, the Ganja region was a battle field for Ottoman-Safavid wars. At that time, it was necessary to build a strong fortress. Ganja Fortress, which was known as “a shield that all Asians relied on”, was built by the commander of Turkish troops in the Caucasus, Ferhat Pasha, on orders from Ottoman Sultan Murat III. The total length of the wall was 3.6 km and height – 8.5-9.5 meters. In 1868, Ganja became a regional cent­re. According to the new general plan drawn up by the regional architect, Igna­tiy Ivanovich Krzyntalowicz, and appro­ved by Emperor Alexander II, the histo­rical centre of the city underwent drastic changes. The fortress was destroyed and a European-style quarter was establis­hed.
