Identity & Location

• Name: Tepe Sialk (Read more on Wikipedia)

• Type: Ancient city–temple archaeological complex (two mounds + two cemeteries)

• Location: Isfahan Province, Kashan, Fin district (SW of Kashan, right side of the Kashan–Fin road)

• National Registration: No. 38, 24 Shahrivar 1310 (15 Sep 1931)

Why Sialk Matters

Sialk is among the most important archaeological sites on the Iranian plateau and one of the oldest known settlements in Central Iran, preserving a long cultural sequence from the Neolithic through the Chalcolithic, Early Urban, Bronze/Iron Ages, and a Median horizon. The site documents:

• The emergence of early villages and hand-built houses in the region;

• Agriculture (wheat, barley) and animal husbandry (cattle, sheep, goat);

• The evolution of ceramics (from coarse hand-made wares to fine wheel-made vessels with human/animal/plant motifs);

• The onset of metallurgy (copper extraction/smelting; furnaces on the south mound);

• Evidence of spinning and weaving (stone/clay spindle whorls);

• Early recording and exchange systems (tokens/counters, seals, local tablets);

• And landmark sacred architecture such as the Sialk ziggurat, regarded as one of the earliest of its kind on the Iranian plateau.

Site Layout

The Sialk complex comprises two mounds and two cemeteries:

• North Mound (Small Sialk, ~5 ha) and South Mound (Large Sialk, ~8 ha), about 600 m apart;

• Cemetery A (~3,500 years BP), ~200 m south of the south mound (parts now beneath a modern boulevard);

• Cemetery B (~3,000 years BP), beneath orchards and fields west of the mounds.

Discovery & Excavations

• Until 1931, the site was unknown to scholarship and locally dubbed the “cursed city.” After objects were transferred to the Louvre, their antiquity prompted Roman Ghirshman to come to Iran; with André Godard he began systematic excavations.

• The French team conducted three seasons (1933, 1934, 1937) on both mounds and the cemeteries; results appeared in 1938 as the two-volume Sialk, Kashan (later translated into Persian).

• From 2001 to 2006, Dr. Sadeq Malek-Shahmirzadi led an Iranian mission over five seasons; publications include: Ziggurat-e Sialk, Sofālgarān-e Sialk, Noghre-kārān-e Sialk, Shekārčiyān-e Sialk, Sialk: Iran’s Oldest Enclosed Village (final report), and Rūstā’iyān-e Sialk (collected studies). This phase also clarified the remains of the Sialk ziggurat.

• Subsequent research continued alongside reported pressures from modern development around the protected buffer, underscoring the need for careful heritage management.

Cultural Phases (Sialk I–VI)

Archaeologists group Sialk’s evolution into six phases (earliest to latest):

Sialk I (c. 8000–7300 years BP)

Small groups in reed/wood shelters; forager–hunters beginning cultivation and animal management; hand-made buff/red wares; stone tools, clay sickles, hand-querns.

Sialk II (7200–6700 BP)

The first village of mudbrick/chineh; consolidated farming and herding; Cheshmeh-Ali painted wares (geometric/plant motifs in black); evidence of spinning/weaving.

Sialk III (6300–5400 BP)

Shift to the south mound; standardized houses (rooms/hearths/niches); copper extraction and regional exchange; invention/adoption of the potter’s wheel with rich human/animal/plant iconography; use of tokens/counters in transactions.

Sialk IV (5300–4900 BP)

Population growth and trade expansion; local political authority; influence of early writing traditions from SW Iran; spread of “rolled-rim” baking plates (likely for bread).

Environmental Hiatus

At the end of Phase IV, parts of the central plateau (incl. Sialk, Ozbaki, Arisman) show a 1,000–1,200-year settlement crisis, likely environmental (e.g., drought).

Sialk V (3600–3000 BP)

Reoccupation dominated by Grey Ware; Cemetery A lies ~100–200 m SW of the mounds (many graves looted in antiquity). Classic scholarship often linked this horizon to incoming Iranian (Aryan) groups.

Sialk VI (3000–2700 BP)

Final occupation; revival of painted/figured ceramics and distinctive long-spouted beakers with mythic motifs (warriors, winged horses, solar emblems); Cemetery B (~217 graves, ~70 intact in early digs). After this phase, Sialk is abandoned, populations dispersing across the Kashan plain.

Architecture & the Ziggurat

Sialk is fundamentally the ruin of one of the earliest ziggurats known on the Iranian plateau—an earthen/clay monumental platform within a broader urban–ritual fabric that includes domestic units (rooms, hearths, niches), revealing urban planning and sacred spatial organization.

Industries & Economy

• Ceramics: From early coarse red/buff hand-made wares to fine wheel-made vessels with ibex, horse, sun, and geometric motifs. In the late phase (Sialk VI) the tall long-spouted beakers with mythic decoration are iconic.

• Metallurgy: Evidence of copper smelting furnaces, copper/bronze/iron objects (mirrors, pins, needles, spearheads, bracelets).

• Textiles: Spindle whorls and weaving-related finds indicate knowledge of spinning and fabric production.

• Herding/Farming: Remains of cattle and sheep/goat; signs of horse use and management; carbonized wheat and barley.

Burials & Society

• Burials are commonly crouched/fetal with grave goods (pottery, ornaments, tools/weapons).

• In later periods, gable/capping elements appear over graves.

• Variation in grave wealth indicates social differentiation (elite/warrior vs. peasant/artisan).

• Interactions between local populations and incoming Iranian groups are reflected in funerary data and material culture (e.g., prominence of the horse).

Museums & Collections

Significant Sialk finds are held at:

• Musée du Louvre (Paris)

• National Museum of Iran (Tehran)

• Fin Garden Museum (Kashan)

• On-site Sialk Base/Exhibition (interpretive displays and film)

Visiting & Practical Info

• Address (recommended): Kashan — Amir Kabir Ave → Amir-al-Momenin St → end of Zolfaghar 10, Sialk Cultural Heritage Base.

• Hours: Typically 09:00–17:00/18:00 (seasonal).

• On site: Open-air trenches, kiln areas, architectural remains, and an indoor exhibition with films and educational panels.

Preservation Challenges

Despite national registration and scholarly importance, reports of modern encroachments (utilities, construction) around Sialk’s primary buffer have surfaced. Effective heritage zoning, responsible public presentation, and sustainable visitation are essential for safeguarding this fragile site.

Summary

Tepe Sialk is a living syllabus of the birth and growth of civilization in Central Iran—from reed-and-wood shelters and rudimentary pottery to the potter’s wheel, copper smelting, a ziggurat, and early recording systems. For scholars and the wider public alike, it is a place where the long trajectory from village to city, and from myth to administration, is preserved in the earth’s layers—an irreplaceable window into Iran’s deep past.
