Poschiavo is first mentioned in 824 as in Postclave though this comes from a later copy of the original document.. In 1140 it was mentioned as de Pusclauio. It was formerly known by the German name of Puschlav. It owes its beauty to the imposing Renaissance style of its courtly 19th century architecture. These palazzi were built by prosperous local residents who had made their fortune abroad, particularly in Spain.
