I don't know if it is Mediterranean style. It is considered though as a Greek traditional style although the white colour was only imposed in 1938. Some say that it was a sanitary measure against cholera (they used a solution of lime at the time, not paint), some others that it was a political measure, to emphasise the power of the dictatorship that ruled Greece. Either way they still paint the houses and the edges of the streets white as part of the Greek folklore!
Thanks for stopping by :)
