Architectural details of Temple of Poseidon

Architectural style and order

The temple follows the Doric order, one of the three classical styles of ancient Greek architecture. Doric temples are known for their plain, cushion-like capitals atop fluted columns and a strong structure without excessive ornamentation.

Materials and construction techniques

Local white marble from the nearby Agrilesa quarries was used in the temple’s construction. The columns were made by stacking cylindrical stone blocks called drums and securing them with metal dowels. Craftsmen carved the flutes and details on-site with precise alignment and spacing, showcasing the advanced engineering skills of the time.

Column design and layout

The original structure featured 34 Doric columns arranged in a single row, surrounding the central chamber or cella on all four sides. The layout was 6 columns wide and 13 columns long. Each column stands about 6 meters tall with 16 vertical flutes. The subtle bulge in the middle of the columns, known as entasis, corrects optical illusions and makes them appear straight from a distance.

Sculptural decoration

While much of the temple’s decorative sculpture is now lost, it once featured carved friezes and metopes with scenes from Greek mythology. These likely included battles with centaurs and episodes from the life of Theseus—Athens’ legendary hero. Traces of paint found on fragments suggest that the temple was once brightly colored, not the plain white we see today.

Orientation and site integration

The temple is strategically oriented to face the sea, offering panoramic views over the Aegean. The position chosen was functional as it served as a landmark for ancient mariners navigating toward Piraeus. Some scholars believe its alignment may also correspond with astronomical events, like the setting sun during the summer solstice.

Architectural comparisons and influence

Nearby, the Temple of Athena Sounias stood on a lower terrace. Unlike the Doric Poseidon temple, it used Ionic features and had a different floor plan. The Temple of Poseidon shares similarities with the Temple of Hephaestus in Athens, especially in size and proportion. Its clean design has influenced many neoclassical buildings across Europe and beyond.

What to see at Temple of Poseidon

Double colonnade corners

The temple’s corners feature two columns on each side, a detail unique to some Doric temples, enhancing structural strength and symmetry when viewed from multiple angles.

Low stylobate platform

The three-stepped base, or stylobate, is subtly curved to counter optical illusions, making the temple appear perfectly level despite the uneven cliff terrain

Distinct column fluting

Each column has 16 flutes instead of the more common 20, possibly for faster construction or visual effect, marking a rare variation in Doric design.

Cuttings for roof beams

Stone grooves and notches still visible at the top of columns and walls reveal how wooden beams once supported the tiled roof.

Masonry join marks

Visible clamp and dowel holes between marble blocks show how iron fastenings secured the structure, offering insight into ancient Greek engineering techniques for earthquake resistance.

Cella foundation remains

The rectangular inner chamber, or cella, is partly preserved, with traces of the central cult statue’s base still visible, marking the temple's sacred core.

Westward orientation

Unusually, the temple's entrance faces west, possibly aligning with sunset rituals or symbolic views over the Aegean, differing from the typical east-facing Greek temples.

Frequently asked questions about Temple of Poseidon architecture

What material was used to build the Temple of Poseidon?

The temple was built using locally quarried marble from Agrileza, a nearby source chosen for its availability and ease of transport to the cliffside site.

Were any colored elements used in the temple’s design?

Traces of pigment suggest parts of the frieze and decorative features were once painted, though most color has faded due to centuries of weather exposure.

How was the temple roof constructed and supported?

Wooden beams supported terracotta roof tiles. Cuttings in the marble indicate how the beams were slotted and anchored into place without visible metal reinforcement.

What remains of the temple’s inner chamber?

The foundation of the cella still exists, including part of the base where a large statue of Poseidon likely stood at the center of the space.

Is there evidence of how the blocks were joined together?

Yes, small square cuttings in the marble blocks show where metal clamps and dowels were inserted to hold stones tightly together without the use of mortar.
