Wednesday 25th May 2016. Ostuni, known as the White City is one of Southern Italy’s most spectacular small towns. Originally the practise of lime washing the town’s houses  as a means of lightening up the dark, labyrinthine medieval streets, but whitewashing was also thought to be a measure in defence against the plague. In the 17^th century a plague killed millions in the area and the infected houses were painted white by using limestone dust mixed with water. The 15^th century cathedral is Ostunis best known landmark as well as the narrow-cobbled streets. The town has a long history being founded some 600 years before the birth of Christ.
