Being situated on fertile lands with good transportation access, the province of Denizli has long been known as an agricultural center and trade hub of the region. In the last 30 years, however, it has shown a remarkable industrial development. The success behind this development is primarily due to the capital transfer to industry, which accumulated in years through hand crafts and weaving together with trading activities. Consequently, Denizli became the second fastest growing city of the Aegean region following Izmir. Gross National Product (GNP) of Denizli is in the order of 2133 US Dollars as of 2001 prices.
