The Campionati Internazionali di Sicilia or International Championships of Sicily, also known as the Palermo Open, was a combined men's and women's clay court tennis tournament founded in 1935 and played annually at the Circolo Tennis Palermo in Palermo in Italy.
The International Championships of Sicily were established in 1935 as a combined tournament for men and women.
In 1955 the Campionati Internazionali di Sicilia were disputed in Messina and won among the men Nicola Pietrangeli who beat in final Fausto Gardini in five sets,[1] and in female tournament Silvana Lazzarino that won in final against Lea Pericoli.
The tournament continued under a joint format until 1971 when the women's event was discontinued.
[2] In 2009 a new successor tournament to this event was established called the Sicilia Classic.
