History & heritage

Thirasia was once part of a single volcanic island, the mythical Strongyli (or Kallisti), together with present-day Santorini. Around 1600 BC the cataclysmic Minoan eruption blew apart the volcano's center, collapsed the island's interior and formed the immense caldera; thus Thirasia was cut off and remained on the western side of the crater.

Thirasia holds a distinct place in Aegean archaeology. Already in 1866–1867, when the island was being quarried for the famous volcanic "Thiraic earth" used in the construction of the Suez Canal, prehistoric buildings and finds came to light — a discovery that preceded the major excavation of Akrotiri in Santorini and first drew scholarly interest to the prehistoric civilization of the region.

In antiquity the island lay in the shadow of the powerful Ancient Thera. After the Roman and Byzantine periods, with the Frankish rule Thirasia passed, together with Santorini, under Venetian dominion and was incorporated into the sphere of the Duchy of the Aegean, all the while enduring pirate raids that forced its inhabitants to build far from the sea.

Under the Ottoman Empire and later, within the modern Greek state, Thirasia remained a poor but proud rural island, its economy based on vineyards, wine and volcanic products. As neighboring Santorini transformed into a world-famous tourist destination, Thirasia was gradually depopulated — and precisely for this reason it preserved intact the authentic look of "old Santorini".

Caldera

The rim of the vast volcanic crater, with an incomparable view toward Nea and Palaia Kameni, the volcano and Santorini — the same legendary sight, but in complete tranquility.

Manolas

The small capital hanging on the cliff, a labyrinth of all-white lanes, arched houses and the quietest sunset of the entire caldera.

Korfos steps and footpath

The paved path with around 250 steps connecting the little harbor of Korfos with Manolas — the traditional ascent, on foot or by mule.

Prehistoric settlement of Thirasia

In the Kimisi area, prehistoric ruins came to light as early as the 1860s, during the quarrying of volcanic "Thiraic earth" — finds that predate even those of Akrotiri.

Vineyards

The low, coiled "kouloura" vines on the black volcanic soil, which produce the distinctive Assyrtiko wine of the volcanic complex.

Potamos

The quiet rural settlement with old stone houses and chapels, where life moves as it did decades ago.

Getting here

Access & transport

How to get there

Thirasia can only be reached by sea from Santorini: by small ferry from Athinios to Riva, or by boat from Ammoudi in Oia to picturesque Korfos (~15–20 min) — the most atmospheric route, through the caldera.

Getting around the island

The island is very small and is explored mainly on foot, along footpaths and steps; a single road connects Riva with Manolas and the settlements, while from Korfos you climb to the main town by steps or by mule.
