Casanova is on the road from Terricciola to Selvatelle. A former feudal castle that rebelled against Pisa in 1164 along with other castles in Valdera and was therefore dismantled by the Pisans before being the scene of the clash between Guelphs and Ghibellines in the late 13th century.
In the village, already mentioned as a castle in 1164, is the ancient Church of St Bartholomew built on the dismantled fortress. Its current appearance is the result of 19th-century renovations. Originally, the church was in fact built of brick, with a simple gabled façade, now embellished by the large gable. The interior has a single apsidal nave, with the presbytery raised and separated by a balustrade and two pairs of columns. The barrel-vaulted roof with dome retains the 19th-century decorations. Above the high altar are three painted terracotta statues depicting the Madonna and Child between St. John and St. Bartholomew, attributed to Giovanni Gonnelli known as the Blind Man of Gambassi (mid 17th century).
The temple-shaped baptismal font is made of marble. On the counter façade is the wooden chancel with the original organ.
In recent years, the hamlet has become home to important international wineries that produce excellent quality wines, also distinguished by the DOC Terre di Pisa.
