Tirana is a city with a rich history dating from the Paleolithic times back 10,000 to 30,000 years ago to the present day. The oldest settlement located in the area of the city was the Cave of Pellumbas, in today's village of Pellumbas. As argued by various archaeologists, Tirana and its suburbs are filled with ancient Illyrian toponyms as its precincts are some of the earliest regions in Albania to be inhabited. One of the ancient monuments, the Tirana Mosaic is believed to have been part of a 3rd century ancient Roman house. Later, in the 5th and 6th centuries, a Paleo-Christian Basilica was built around this site. Tirana was founded as a city in 1614 although the area has been continuously inhabited since antiquity. An almost unimportant centre until the beginning of the 20th century, the Congress of Lushnjë proclaimed Tirana as the capital of Albania, which had acquired Independence in 1912.
