About Oia, Santorini
Oia sits at the northern tip of Santorini, on the rim of a flooded volcanic crater. The caldera took much of its present shape in the Minoan eruption of the late Bronze Age, one of the largest volcanic eruptions in human history, which blew out the middle of the island and left a ring of cliffs layered in red, black and ochre lava and ash.
The village grew along the top of those cliffs. Many of its houses are cave houses, dug back into the soft volcanic rock and closed with a whitewashed front, which kept them cool in summer and warm in winter. In the 19th century Oia was a town of sea captains and merchants, and their larger mansions still stand along the main street.
An earthquake in 1956 damaged much of the village and many people left. Oia was slowly restored from the mid-1970s onwards, keeping its traditional style, and today the white houses, blue-domed churches and windmills are among the most photographed views in Greece.
Every evening crowds gather at the ruins of the Venetian castle at the western end of the village to watch the sun go down over the caldera. Below the cliff, a few hundred steps zig-zag down to Ammoudi, a tiny harbour with fish tavernas at the water’s edge.
The diorama
The diorama turns the caldera wall into the front of a floating block, with the village stacked on terraces along its rim. The houses are close to scale: barrel-vaulted cave houses with blue-framed doors and windows, patios with infinity pools, parasols and bougainvillea, blue-domed churches with white bell gables, and two whitewashed windmills with thatched caps by the castle ruin at the western tip. The layered lava cliff below is compressed so it fits the block.
A path of zig-zag steps with white parapets runs down the cliff to the quay of Ammoudi, with its fish tavernas and moored boats. The scene faces west, so the reel’s golden hour is a sunset: a big pixel sun sinks behind the caldera, and then the village lamps come on and the domes and windmills are lit up for the night.
Things to spot
- Donkeys on the steps, one with a rider
- A catamaran and a fishing boat passing below the cliff
- The sunset crowd at the castle ruin
- The windmill sails turning
- Gulls circling over the caldera
What we simplified
- The cliff is about five times lower than the real caldera wall, so the village and the harbour fit on one block.
- The houses and churches are typical of Oia rather than copies of particular buildings, and the village is shortened along the rim.

How was this pixel-art diorama of Oia made?
It is a real-time Three.js scene on this page, drawn at 360 × 640 pixels with outlines and a small palette and scaled up without smoothing. The cliff is about five times lower than the real caldera wall so the village and the harbour fit on one block. Press “Explore in 3D”, drag to turn it, and switch between day, dusk and night.
