The word “vardiola” originates probably from the word guardiola (a common castle term meaning guard or observatory from the Italian word “guarda”). It is used for the various watchtowers that the Venetians built on the coasts of the Ionian islands. There are vardiolas in Kythira, Cephalonia and Zakynthos. Some of them are included in Kastrologos. Probably, there are many more. We do not know (in this site) if the name “Vardiola” is used for watchtowers in other areas outside the Ionian islands.
The Vardiolas of Zakynthos have a very particular design: small dimensions, strong stone walls with a square-pyramid-shaped roof.
Most of the vardiolas in Zakynthos were constructed during the administration of the Venetian Proveditore (Governor) Claudio Gherardini who held this position during the period 1768-1770.
