Paros exported the translucent lychnites marble that became the Winged Victory of Samothrace. Three days trace that story: Helena's Ekatontapiliani, the Venetian Kastro raised from temple drums, the Archilochus stele, and the abandoned tunnels of Marathi.
Founded 326 CE on Helena's vow, rebuilt under Justinian c. 560 CE. Three churches in one: the main basilica, the 4th-century baptistery with its cruciform sunken font, and the chapel of Agios Nikolaos with ancient marble columns.
Home to a fragment of the Parian Chronicle, a marble chronology carved c. 264 BCE listing events from Cecrops onward, plus the Archilochus stele found in 1949 and a 6th-century BCE Gorgon. Open 08:30-15:30, closed Tuesdays.
Built 1260 CE by the Sanudo-Venier lords using column drums and architrave blocks quarried from the 6th-century BCE Temple of Athena and a temple of Aphrodite. The north wall reads as a striped mosaic of stacked ancient marble.
The lanes behind the Kastro follow the medieval Frankish street plan, ending at the twin churches of Agios Konstantinos on the ancient acropolis terrace, where geometric-period foundations survive beneath the whitewash.
The harbour tavernas grill octopus over charcoal and pour Monemvasia and Mandilaria wines from Paros vineyards — grape varieties documented on the island since the Venetian period, when Parian wine was shipped to Constantinople.
The tunnels that produced lychnites marble for the Venus de Milo, Hermes of Praxiteles and Napoleon's tomb. Two galleries descend into the hillside; the relief of the Nymphs is carved at the entrance of the Cave of the Nymphs shaft.
Paros's medieval capital, built inland in the 15th century so pirates could not see it from the sea. Agia Triada (1830) is faced entirely in Parian marble, and the village's marble-paved lanes were deliberately laid as a maze.
A 1,000-year-old paved trail, marble-flagged and roughly 3.5 km, that carried marble and produce across the island's spine. Sections of the original Byzantine paving and drainage channels survive intact along the ridge.
A defensive settlement whose outer houses form a continuous wall with two gated entrances; the churches of Agios Ioannis Prodromos and Agios Spyridon are joined back-to-back over the archway you pass through to enter.
An excavation since 1997 revealing a large archaic sanctuary of Apollo with reconstructed marble columns, dated to the 6th century BCE and linked to Parian control of the sea route to Delos.
The 15th-century Venetian sea-fort at the harbour mouth is now half submerged; you can wade the causeway to its remaining tower. Naoussa bay sheltered Russian Admiral Orlov's fleet in 1770-1775 during the Orlov Revolt.
Household looms, embroidered Parian bridal costumes and fishing gear documenting island life before tourism, alongside displays on the Naoussa sponge and fishing fleets that sustained the village into the 1960s.
A 17th-century whitewashed monastery on the Korakas headland, and inland the walled Venetian-era Petaloudes estate whose cisterns and irrigation channels still feed the valley planted by its 17th-century owners.
