The **Ancient Olynthos** is one of the most important archaeological sites in Halkidiki and globally known to historians and architects: it preserves one of the **best-preserved examples of the Hippodamian system**, the first systematic urban planning in history.
On the **North Hill** of the site, visitors can clearly see the layout: wide avenues intersected perpendicularly by narrower streets, dividing the city into **perfectly rectangular city blocks**. More than **100 ancient houses** have been excavated, providing a rare, detailed picture of daily life in classical Greece — from kitchens and baths to men's quarters.
Olynthos hosts some of the **oldest known mosaic pavements** of Greek art. The mythological representations featuring **Bellerophon and the Chimera** and **Dionysus on a chariot** stand out, made with natural pebbles in white and dark colors.
Since **432 BC**, when the inhabitants of many coastal cities settled there, Olynthos became the capital of the **Chalcidian League** and a key economic and military center of the region. It was completely destroyed by **Philip II** in **348 BC** — and it is precisely this abrupt abandonment that preserved the city so well for archaeologists.
An **Archaeological Museum** operates on-site with findings from the excavations
