Torralba is a countryside region South of Alayor, that has been dwelling since prehistoric times. There are scattered groups of cottages and megalithic remains in the area.
Torralba de Sa Sorda and its traditionally whitewashed walls.
Farm houses in Menorca stand out often for the bright white of the plaster of their walls. That is due to the lime, a white caustic alkaline substance consisting of calcium oxide, obtained by heating limestone. It is unexpensive and easy to apply.
In some parts of the island there are still standing some decrepit and obsolete buildings that once were used as lime kilns. Some are over 500 years old.
