Hasansu, Zayamchai, and Tovuzchai uncovered from the BTC pipeline have revealed early Iron Age artifacts. Azerbaijani carpets can be categorized under several large groups and a multitude of subgroups. Scientific research of the Azerbaijani carpet is connected with the name of Latif Karimov, a prominent scientist and artist. It was his classification that related the four large groups of carpets with the four geographical zones of Azerbaijan, Guba-Shirvan, Ganja-Kazakh, Karabakh and Tabriz. Cuisine The traditional cuisine is famous for an abundance of vegetables and greens used seasonally in the dishes. Fresh herbs, including mint, cilantro (coriander), dill, basil, parsley, tarragon, leeks, chives, thyme, marjoram, green onion, and watercress, are very popular and often accompany main dishes on the table.

Among the most recent architectural monuments, the Baku subways are noted for their lavish decor. The task for modern Azerbaijani architecture is diverse application of modern aesthetics, the search for an architect's own artistic style and inclusion of
