Palu is located in Western Armenia, in the province of Arghanamaden of the province of Kharberd, which roughly corresponds to the historical province of Balahovit. According to legend, Balahovit was named because of the extensive cherry orchards in this place. The high-altitude rock near the city, on which the fortress of Palu was built in ancient times, was called Mount Saint Mesrop, where Mesrop Mashtots stayed for seven weeks and finally reworked the Armenian letters he invented. A 29-line cuneiform inscription of Urartian King Menua I (9th-8th centuries BC) has been found here. Since the middle of the XIX century, the fortress has already been destroyed and lost its beauty.
