Nor Hachn is one of the towns in the Kotayk Region of Armenia which was founded in 1953. The city is located on the right bank of Hrazdan River, to the west of the Arzni canyon, close to the Arzni-Shamiram canal. It has an average height of 1,920 m above sea level.
Mount Hatis is 12 km east of Nor Hachn, while the Mount of Ara is 13 km northwest of the town. The climate is continental with hot summers and cold winters.
The town is named in memory of the Armenian town of Haçin in Cilicia, where a group of local fedayis organized a military resistance against the Turkish forces in 1920. Unfortunately, only 365 people could survive and escape from Hacin.
In 1974, a memorial dedicated to the Haçin resistance was erected in Nor Hachn. The memorial is home to the museum of "History of the Armenians of Cilicia". The museum depicts the history of the Armenian Kingdom of Cilicia, the culture of the Cilicia region, as well as the history of Haçin and the resistance of 1920 against the Ottomans.
The Holy Saviour's Church consecrated in July 2015, is the main church of the town.
