Castiglione della Pescaia (Italian pronunciation: [kastiʎˈʎoːne della peˈskaːja]; abbreviated by locals as Castiglione or Castiglioni), is an ancient seaside town in the province of Grosseto, in Tuscany, central Italy. Situated in the Grossetan Maremma, the modern town grew around a medieval 12th century fortress (Italian: castello) and a large fishery, from which it acquired its designation. Today Castiglione is a very popular tourist destination with attractions that include beaches, natural parks, biking trails, historical Etruscan archaeological sites, a panoramic mediaeval hamlet as well as the natural reserve Diaccia Botrona, a swampy humid environment of historical relevance whose endangered wildlife comprise pink flamingoes, mallards and ducks.
Castiglione della Pescaia is home to the second most expensive street in Italy for property prices, with average values exceeding those of homes in every other Italian street except one, also in Tuscany.
