Denizli is a growing industrial city in the mountains of southwestern Turkey. Denizli attracts many visitors to the nearby mineral-coated hillside hot spring of Pamukkale, and the ancient ruined city of Hierapolis, as well as ruins of the city of Laodicea on the Lycus, the ancient metropolis of Phrygia. Also in the district of Honaz about 10 miles west of Denizli is what was, in the 1st century A.D., the town of Colossae. A vibrant center of production industries focused on exportation, Denizli is also frequently cited, along with a number of other Turkish cities, as one of the foremost examples of "Anatolian Tigers" in reference to its rapid pace of development. In summer the weather is very hot, the winters may occasionally be very cold with snow on the mountains that surround the city. Springs and Autumns are generally more rainy.
