[1] This place holds significant historical importance due to the presence of well-preserved archaeological remains, specifically a Roman aqueduct.

Mansourieh, situated on a hilltop just 10 kilometres east of Beirut, serves as the gateway to Northern Matn, offering panoramic views of the capital.The name originates from the Arabic: منصور (translit.

Upwards to the east, Mansourieh merges with Ain Saadeh and Monte Verde-Beit Mery, and slopes downhill westwards to Mkalles and Sin el-Fil.

Mansourieh lies on the main road running from Beirut through Sin el-Fil and Mkalles, winding up the mountain to reach Baabdat, Bikfaya, and upper Matn.

The old road showcases scenic views of Beirut alongside charming houses, while the Mansourieh highway bustles with food chains, retail shops, and high mobility traffic.

The Beirut River flows east to west from Lebanon's mountains passing through the south of Mansourieh to the Mediterranean Sea.

During the Roman period, with the expanding urbanization of Beirut, the demand for running water outgrew the capacity of the existing wells and springs.

Source:[12] The Hajj family history traces back to the 17th century when its ancestor Hanna el-Hajj fled his hometown of Beit Mellat, a village in Akkar in the North.

[13] Little is known of Hanna, but his journey and dwellings in different places (Byblos, Antelias, Achrafieh, Chiyah), proves him as an expedient man willing to fight for his rights and possessions.

Quarrels with local inhabitants forced him to change places, finally settling in the Zireh-Daychounieh area south of Mansourieh.

In Zireh Hanna built a small church, erect to this day although disused, known as Mar Gergis (Arabic for Saint George), where he was eventually buried.

According to accounts, a group of men encountered harsh weather while traveling to Mtein village, necessitating an overnight stay at Hanna's residence.

Overwhelmed by their host's generosity, they related the episode to the Emir who, somewhat envious, decided to get rid of Hanna and dispatched his troops to that effect.

[13] The family first moved to Ain el-Qabou near Baskinta, Trad then spent winters in Beirut, and Hamouche in Mansourieh where he eventually settled.
