The Castle of Casarano was built in the 17^th century on a pre-existing church of the 15^th century. Its rooms are large and richly decorated. It was built for the D’Aquinos and they wanted it to be a wonderful castle. The De Judicibus Palace is another important palace. Its facade is beautiful and has a portal. The inside is finely decorated and the ceiling are covered with frescos. The Parish Church is dedicated to Our Lady of the Annunciation. It was built at the end of the 17^th century on the rests of a 16^th century structure. The façade has a beautiful portal, three niches and two stately columns. It is an aisleless church and has paintings and frescos on the walls. The 18^th century painting by Oronzo Tiso represents three children among the flames. The church of the Virgin has taken the place of the Church of the Annunciation. It dates to the 18^th century and inside there are beautiful altars and paintings by Oronzo Tiso. During the works of restoration people found two frescos of the 18^th century. The church of St Mary of the Cross was built in the 5^th century and is one of the few monuments of the Byzantine period in the Salento. It has a nave and two aisles, some mosaics and the frescos representing the life of Jesus, the Virgin with the Child and the Archangel Gabriel. The Church of St Domenico dates probably to the 1536. It has a Latin cross plan, some finely decorated altars and a painting representing the Virgin. Next to the church there is the former Convent of the Dominican Friars. It was built in the 17^th century, its stately façade is very elegant. It is now the Town Hall. The Church of St Peter dates to the 18^th century and is very simple. Inside there are five paintings of sacred subjects by Oronzo Tiso. The Church and the Convent of St Mary of the Angels were built in the 16^th century and the soil was given by the lord of the time, Gurello Filomarini. Some old fortified farms can still be seen outside the urban area.

The people of Casarano have three nicknames: “sacare” (snakes), “machi” (foolish people) and “zocculari”(cunning people). The first nickname was created by the people of Melissano. The second and the third nicknames are one opposite to the other, because the first refers to people who do not react to insults, while the other means they are shrewd and clever.
