Nazarloo was developed and turned into a large and flourished village during Qajar era. It was of a great importance for Khans and because of its large area and resources, sometimes several lords shared it simultaneously. An old document from Iran's National Library shows that Nazarloo was exchanged for 4 Other villages in Marand, by Haji Hoseinqoli Khan Nezam-o-Doleh Donbali governor of Tabriz city in that time. As is quoted from old residents of Nazarloo, there was a series of old houses and gardens around Nazarloo during Qajar era which had become abandoned and called Kode lands, so that old Nazarloo was limited to these lands, today's Motahari St. in the east, and Seyedlar Alley in the north. This was so until a group of Tabrizi people came there in the mid 1330 and made Koda a developed and prosperous land by digging wells that provided water supply. After a few years these lands were bought by Nazarloo's people and joined to it. There were also two very old cemeteries in Nazarloo, one in Pir Moosa lands next to today's medical center and another was located at today's Shahid Madani Elementary school. In an astonishing story it is said that in the latter one, bodies were buried over each other in the underground cellars. Among historical remains from Islamic era, there are two holy shrines called Emamzadehs in the west of Nazarloo and almost nothing is known about their death time and burial. There is also another holy shrine outside the village next to Nazarloo-Zinab way in Karamali lands, once it had a clay dom encircled it but today it is under construction. A few decades ago there were two stone made rams beside the Eamazadehs next to today's Medical center and they can be traced back to Aq Qoyunlu and Qara Qoyunlular Dynasty. Ram is considered to be the symbol of power and authority between Turkish people and similar sculptures can be found in their historical territory all over Iran and neighboring countries. Unfortunately, these stone arts were displaced and removed from the site in the 70th Hijri Shamsi, as a matter of ignorance and theft. There can be found remains of an old mosque called Oba mosque outside Nazarloo in the east and it is said that the building belonged to nomad people who lived around Nazarloo. Some people of Nazarloo said to immigrated from two old villages namely Sarabad and Kohneh Kand. According to rough estimations both villages were totally abandoned around 1300 Hijri Shamsi and then destroyed. Sarabad was located in farm lands between Nazarloo and Zinab village and Kohneh Kand was located in the South of Nazarloo. There are also some people living in Khoy, a large city in West Azerbaijan province, who relate themselves to Nazarloo and many of them carry the name in their surnames. An old notebook from Qajar's last years of ruling, which belonged to Nozhat-O-Doleh where her accountants and counselors kept yearly record of taxes of a few of her properties including Nazarloo.
