The remains of the village are located in a ravine beside an 18th-century farmhouse 2 kilometres (1.2 mi) southwest of Mottola.
In 1081, the monasterium Sancti Angeli in Casali Rupto was granted to the Benedictine monastery of La Trinità della Cava dei Tirreni.
[2] In 1231, a judicial panel composed of Henry of Morra, Roffredo di San Germano and Pier della Vigna confirmed that Casalrotto belonged to La Cava against the claims of the nobleman Gualtiero Gentile.
[3] Casalrotto consists of about one hundred natural karst caves enlarged by human action to make residences and other spaces.
To the northeast is a cave with traces of paint that might have been the church of Santa Maria, built between 1155 and 1165.
