Pescasseroli lies in a basin at the entrance to the Alta Valle del Sangro at m. 1167 above sea level. This plateau full of pastures is surrounded by centuries-old woods and suggestive mountains. Pescasseroli is a town where the symbiosis between nature and architecture is evident: the inhabited center is in perfect harmony with the natural wonders that surround it.

The urban core, in a flat position, has developed around the ancient abbey and is characterized by traditional masonry constructions of stones and mortar, adorned by particular windows with local cut stone, called "gentle stone" from the name of the mountain of the same name.

Piazza S.Antonio, so called due to the presence of a church that has now disappeared, is the fulcrum of Pescasseroli's life: it is colored by beech trees and perfumed by the small flowers of the lime trees and is adorned, as well as by the Town Hall, by a graceful fountain, surmounted by a statuette of the Immaculate Conception.
