The Tower of Grivas

A nearly forgotten circular fortress above the turquoise waters of Koutalas reveals the untold mining history of ancient Serifos.

Serifos

The sun falls at a slant on the schist, drying it into shades of brown and reddish ochre, as the path climbs toward a hill that towers above the bay of Koutalas. The wind here never quite stops; it whistles through wild grasses and shrubs, carrying the scent of thyme and sea salt. And there, at the summit, a circle of stone awaits you, having resisted time for more than two thousand years: the Tower of Grivas, known to locals also as the White Tower.

A fortress that watched over the sea and the mines

Serifos was not always just the rugged, hawk-shaped island crowned by its Chora that we see today. In antiquity it was known throughout the Aegean for its ores — mainly iron and copper — a wealth that needed protection. That is why the island became dotted with fortified towers, stone outposts built on high ground with a clear line of sight to the sea and to the mining areas.

The Tower of Grivas is the most impressive of those that survive. Its circular plan, its sturdy masonry of roughly hewn stones, and its strategic position above Koutalas all attest to a dual role: to watch over the passages of ships loading ore, and to give early warning of raiders and pirates.

The architecture of endurance

It is the tower’s geometry that takes your breath away first. The stone cylinder rises with a severity that needs no ornament to command attention; its power lies in the mass itself, in the way each stone fits against the next without mortar, using a technique the ancient inhabitants of the Cyclades had mastered over centuries.

Resting your palm on the rough surface of the stone, you feel the warmth it has absorbed from the sun all day. It is an almost intimate sensation, as if touching something alive — a structure that has survived earthquakes, storms, and the ceaseless erosion of the Aegean wind.

A view that justifies the climb

Reaching the summit, the landscape opens abruptly in every direction. The bay of Koutalas spreads out below in a blue that shifts tone with the depth of the water, from a nearly transparent green near the shore to deep blue further out. Around you, the bare slopes of Serifos stand out like a living sculpture, with no trees to hide the contours of the land.

On clear days, the eye travels as far as the neighboring islands, a reminder of just how strategic this position was for anyone wishing to control the sea routes of the western Cyclades.

Traces of a forgotten daily life

Around the tower, the ground still conceals scattered traces of human presence — pottery fragments, remnants of older structures, paths that once led to mine galleries. Walking among them, you realize this place was never isolated; it was a hub of labor, watchfulness, and survival for people who lived here centuries before us.

The silence today is almost absolute, broken only by the wind and the distant call of some bird. It is hard to imagine the noise that once filled this place when the tower was in full operation, with guards scanning the horizon and workers descending toward the mines.

Serifos does not reveal itself easily; it takes a climb, sweat, and silence to give up its secrets.Traditional view of the island

Descending the hill, with the sea glinting once more before you, you understand why the Tower of Grivas remains one of Serifos’s most authentic encounters with its own past. It is not a monument that impresses through size or grandeur; it impresses through its sheer persistence in staying upright, a witness to an era when this island was both a source of wealth and a target of ambition. A visit here is an invitation to see Serifos beyond its beaches — as a place with a deep, harsh, and captivating history.

Practical information

  • The tower stands above the bay of Koutalas, on the southern side of Serifos.
  • A short walk over uphill, uneven terrain is required — wear closed shoes.
  • Morning or late-afternoon hours are best, away from the summer heat.
  • Bring water, a hat, and sunscreen, as there is no shade along the route.
  • Pairing the climb with a swim in the bay of Koutalas afterward is ideal.
