Lahij is one of the most ancient human settlements in Azerbaijan. The Lahij District is located in the Ismayilli region of the Republic of Azerbaijan, on the southern slopes of the Greater Caucasus Mountain Range at a height of 1211 meters above sea level. Being situated on the left bank of the River Ghirdiman and the slopes of the Niyal Mountain Chain, the settlement of Lahij is a unique living district, with its unusual planning lay out, transport systems, and its public, private and religious buildings. Lahij is an example of early urbanization and architecture, as shown by its cobbled streets and squares, together with its developed sewerage systems and water pipelines.
Earthquakes frequently occur in the region, and, as a result, a specific style of building construction has developed – which include certain styles and techniques in crosscutting stone and installation of wood. The ancient dwelling houses in Lahij have remained unchanged, as, during the past centuries, there have not been any significant changes in the urban planning.
