Oia – a small and spectacular town perched on the crescent-shaped clifftop of the caldera on Santorini island in Greece. It is probably the most famous of all villages of Santorini. It is known throughout the world for its quiet life and fantastic sunset. It is Oia where there are many of the blue domed buildings you see in most of the postcards or photographs of Santorini.
By the way, do you know why the main color of the buildings in Santorini is blue and white?
With little to no wood available, the majority of the buildings on the islands were originally constructed out of dark, volcanic stone. The stone was a great insulator, but the color of the stone absorbed the heat making being inside on a hot day unbearable. Painting the buildings white to reflect the harsh sunlight was a necessary and practical way to stay cool. The color ‘blue’ was added to tone down the extremely white limestone plaster. Most of the households had a blue colored cleaning agent called ‘loulaki’ which was added to the limestone to give it a blue color.
Currently the Greek government has mandated that all buildings must be painted in blue and white.
