Pamukkale


Pamukkale, meaning "cotton castle" in Turkish, is a natural site in Denizli in southwestern Turkey. The area is famous for a carbonate mineral left by the flowing water. It is located in Turkey's Inner Aegean region, in the River Menderes valley, which has a temperate climate for most of the year.
The ancient Greco-Roman city of Hierapolis was built on top of the white "castle" which is in total about long, wide and high. It can be seen from the hills on the opposite side of the valley in the town of Denizli, 20 km away.
Known as Pamukkale or ancient Hierapolis, this area has been drawing the weary to its thermal springs since the time of Classical antiquity. The Turkish name refers to the surface of the shimmering, snow-white limestone, shaped over millennia by calcium-rich springs. Dripping slowly down the vast mountainside, mineral-rich waters foam and collect in terraces, spilling over cascades of stalactites into milky pools below. Legend has it that the formations are solidified cotton that giants left out to dry.
Tourism is and has been a major industry in the area for thousands of years, due to the attraction of the thermal pools. As recently as the mid-20th century, hotels were built over the ruins of Hierapolis, causing considerable damage. An approach road was built from the valley over the terraces, and motor bikes were allowed to go up and down the slopes. When the area was declared a World Heritage Site, the hotels were demolished and the road removed and replaced with artificial pools.
Overshadowed by natural wonder, Pamukkale's well-preserved Roman ruins and museum have been remarkably underestimated and unadvertised; tourist brochures over the past 20 years have mainly featured photos of people bathing in the calcium pools. Aside from a small footpath running up the mountain face, the terraces are all currently off-limits, having suffered erosion and water pollution at the feet of tourists.

Geology

Pamukkale's terraces are made of travertine, a sedimentary rock deposited by water from the hot springs.
In this area, there are 17 hot water springs in which the temperature ranges from to. The water that emerges from the spring is transported to the head of the travertine terraces and deposits calcium carbonate on a section long covering an expanse of to. When the water, supersaturated with calcium carbonate, reaches the surface, carbon dioxide de-gasses from it, and calcium carbonate is deposited. Calcium carbonate is deposited by the water as a soft gel which eventually crystallizes into travertine.

Archeology

There are only a few historical facts known about the origin of the city. No traces of the presence of Hittites or Persians have been found. The Phrygians built a temple, probably in the first half of the 7th century BC. This temple, originally used by the citizens of the nearby town of Laodicea, would later form the centre of Hierapolis.
Hierapolis was founded as a thermal spa early in the 2nd century BC within the sphere of the Seleucid Empire. Antiochus the Great sent 2,000 Jewish families to Lydia and Phrygia from Babylon and Mesopotamia, later joined by more from Judea. The Jewish congregation grew in Hierapolis and has been estimated as high as 50,000 in 62 BC. Hierapolis became a healing centre where doctors used the thermal springs as a treatment for their patients. The city began minting bronze coins in the 2nd century BC. These coins give the name Hieropolis. It remains unclear whether this name referred to the original temple or honoured Hiera, the wife of Telephus, son of Heracles and the Mysian princess Auge, the supposed founder of Pergamon's Attalid dynasty. This name eventually changed into Hierapolis,. In 133 BC, when Attalus III died, he bequeathed his kingdom to Rome. Hierapolis thus became part of the Roman province of Asia. In AD 17, during the rule of the emperor Tiberius, a major earthquake destroyed the city.
Through the influence of the Christian apostle Paul, a church was founded here while he was at Ephesus. The Christian apostle Philip spent the last years of his life here. The town's Martyrium was alleged to have been built upon the spot where Philip was crucified in AD 80. His daughters were also said to have acted as prophetesses in the region. During the 4th century, the Christians filled Pluto's Gate with stones, suggesting that Christianity had become the dominant religion and begun displacing other faiths in the area. Originally a see of Phrygia Pacatiana, the Byzantine emperor Justinian raised the bishop of Hierapolis to the rank of metropolitan in 531. The Roman baths were transformed to a Christian basilica. During the Byzantine period, the city continued to flourish and also remained an important centre for Christianity.

Museum

In this museum, alongside historical artifacts from Hierapolis, there are also artifacts from Laodiceia, Colossae, Tripolis, Attuda and other towns of the Lycos valley. In addition to these, the museum has a large section devoted to artifacts found at Beycesultan Hüyük that includes some of the most beautiful examples of Bronze Age craft.
Artifacts from the Caria, Pisidia and Lydia regions are also on display in this museum. The museum's exhibition space consists of three closed areas of the Hierapolis Bath and the open areas in the eastern side which are known to have been used as the library and gymnasium. The artifacts in open exhibition space are mostly marble and stone. Hierapolis is broken down into ruins.

Tourist attraction

Pamukkale is a tourist attraction. It is recognized as a World Heritage Site together with Hierapolis. Hierapolis-Pamukkale was made a World Heritage Site in 1988.
The underground volcanic activity which causes the hot springs also forced carbon dioxide into a cave, which was called the Plutonium, which here means "place of the god Pluto". This cave was used for religious purposes by priests of Cybele, who found ways to appear immune to the suffocating gas.
Tadpoles can be found in the pools.
Hot air balloon flights are being organized at the sunrise

Protecting the thermal waters

The hotels built in the 1960s were demolished as they were draining the thermal waters into their swimming pools and caused damage to the terraces. The water supply to the hotels is restricted in an effort to preserve the overall site and to allow deposits to regenerate.
Access to the terraces is not allowed and visitors are asked to follow the pathway.
