History of Blinds

The traders of Venice first saw, what we now call Venetian Blinds, in Persia. They brought back home these blinds and called them Persianas-of/from Persia.

In 1794 in Venice, Italy, these Persianas, made from horizontal slats, were developed and manufactured and became know as Venetian Blinds – of/from Venice.

In Italy, Spain and Portugal, the Venetian blind is still called Persianas.
