The ground and the access
Megalochori sits inland in the south of the island, on ground that is generally competent and better suited to conventional construction than the rim. The village core is a compact network of narrow lanes with vehicle access to the edges.
What distinguishes it is what is underground. The village is built over and around canava — vaulted cellars cut and built partly below ground for wine storage, exploiting the stable temperature that makes yposkafo comfortable for the same reason. Many properties have one, and many owners do not fully know its extent.
That matters practically: an underground vault beneath a property is a structural element, a potential damp path, and occasionally an unexpected opportunity for space. It gets surveyed rather than assumed.
What is built here
Traditional vaulted houses in lime construction, canava cellars, courtyard properties, and cisterns — plus later additions and increasing conversion to accommodation and high-end residential.
- Canava conversion, which is genuinely rewarding and technically demanding — a partly buried vault has the same moisture physics as a cave house. See cave house damp proofing.
- Cisterns, often intact and worth restoring. See water cisterns.
- Lime construction throughout, where cement repair causes the usual damage. See plastering.
- Vaulted structure, where the geometry is doing the work. See masonry and stonework.
What matters most on a job in Megalochori
- Survey what is underneath. Canava and cisterns are frequently more extensive than the owner realises, and they are structural.
- Use compatible materials. This is the settlement where cement repair does the most visible damage to the most valuable stock.
- Treat a canava as a cave. Vapour-open finishes, designed ventilation, and surface water routing above it.
- Restore the cistern. On a property with a large roof and terrace catchment, it is a genuine asset rather than a heritage feature.
- Design within the designation. The core is protected and its coherence is the reason the village is valuable.
Questions people actually ask
Can a canava be converted to living space?
Frequently yes, and it makes excellent space — stable temperature, remarkable character. It needs treating as a cave: breathable finishes, designed ventilation, and control of surface water above.
How do I find out what is under my property?
A survey, and it is worth doing before design. Buried vaults and cisterns are common here and they are both structural and useful.
Why does my vaulted room keep getting damp?
Usually impermeable finishes trapping moisture, and sometimes water routing above. Both are fixable, and neither is fixed by sealing further. See damp and humidity.
Is Megalochori as restricted as Oia?
It is a designated settlement with real controls, and the character being protected is different — an intact inland village rather than a caldera skyline. Check the specific requirements for your property.
Can I use modern materials in a restoration here?
Where they are compatible, yes. On lime-built vaulted structure the constraint is physical rather than aesthetic: the wall has to be able to dry.
