|Location||Isfahan Province, Iran|
Tepe Sialk (Persian: تپه سیلک) is a large ancient archeological site (a tepe, "hill" or "mound") in a suburb of the city of Kashan, Isfahan Province, in central Iran, close to Fin Garden. The culture that inhabited this area has been linked to the Zayandeh River Culture.
The Sialk ziggurat was built around the 3000 BC. A joint study between Iran's Cultural Heritage Organization, the Louvre, and the Institut Francais de Recherche en Iran also verifies the oldest settlements in Sialk to date back from 6000-5500 BC.
Sialk, and the entire area around it, is thought to have originated as a result of the pristine large water sources nearby that still run today. The Cheshmeh ye Soleiman ("Solomon's Spring") has been bringing water to this area from nearby mountains for thousands of years. The Fin garden, built in its present form in the 17th century, is a popular tourist attraction. It is here that the kings of the Safavid dynasty would spend their vacations away from their capital cities. It is also here that Piruz Nahavandi (Abu-Lu'lu'ah), the Persian assassin of Caliph Umar, is buried. All these remains are located in the same location where Sialk is.
Tepe Sialk was excavated for three seasons (1933, 1934, and 1937) by a team headed by Roman Ghirshman and his wife Tania Ghirshman. Studies related to the site were conducted by D.E. McCown, Y. Majidzadeh, and P. Amieh. Excavation was resumed for several seasons between 1999 and 2004 by a team from the University of Pennsylvania and Iran's Cultural Heritage Organization led by Sadegh Malek Shahmirzadi called the Sialk Reconsideration Project. Since 2008 an Iranian team led by Hassan Fazeli Nashli and supported by Robin Coningham of the University of Durham have worked at the northern mound finding 6 Late Neolithic burials. 
Artifacts from the original dig ended up mostly at the Louvre, while some can be found at the British Museum, the Metropolitan Museum of Art in New York, and the National Museum of Iran and in the hands of private collectors.
These artifacts consisted of some very fine painted potteries.
The northern mound (tell) is the oldest; the occupation dates back to the end of the seventh millennium BC. The mound is composed of two levels: Sialk I (the oldest), and Sialk II.
Sialk I level architecture is pretty rudimentary. Tombs containing pottery have been uncovered. The ceramic is initially rather rough, then becomes of better quality with the time.
In sub-periods 3, 4 and 5, the pottery has a clear surface with painted decoration. Stone or bone tools are still used.
The Sialk II level sees the first appearance of metallurgy. The archaeological material found in the buildings of this period testifies to increasing links with the outside world.
The south tell includes the Sialk III and IV levels. The first, divided into seven sub-periods, corresponds to the fifth millennium and the beginning of the fourth (c. 4000 BC). This period is in continuity with the previous one, and sees the complexity of architecture (molded bricks, use of stone) and crafts, especially metallurgical.
Evidence demonstrates that Tepe Sialk was an important metal production center in central Iran during the Sialk III and Sialk IV periods. A significant amount of metallurgical remains were found during the excavations in the 1990s and later. This includes large amounts of slag pieces, litharge cakes, and crucibles and moulds.
Sialk IV level begins in the second half of the fourth millennium, and ends with the abandonment of the site at the beginning of the third millennium. For the oldest sub-periods of the Sialk IV, there are links with the Mesopotamian civilizations of Uruk and Jemdet Nasr.
Later on, the material is similar to that of Susa III (Proto-Elamite level), so this is where the Proto-Elamite horizon at Sialk is located, as is also evidenced by the discovery here of some Proto-Elamite clay tablets.
The ruins of what would be the oldest Ziggurat in the world are found at this same Sialk IV level.
Second millennium BC
After an abandonment of more than a millennium, the Sialk site is reoccupied in the second half of the second millennium. This last phase of occupation of the site is divided into two periods: Sialk V and Sialk VI. The archaeological material of these two levels has been mostly found in the two necropolises, called necropolis A and necropolis B.
The first represents the Sialk V level. Here are found weapons and other objects in bronze, as well as jewelry, and some iron items. The ceramic is gray-black, or red, sometimes with some decorations that consist of geometric patterns, and can be compared to items coming from the sites in Gorgan valley (the later levels of Tureng Tepe, and Tepe Hissar).
