The first mention of Cascina is from a document of 750 AD. The origin of the name is still uncertain, but it could derive from
Casina ("Small House"), or from the creek that crossed it (now disappeared), or from an
Etruscan personal name, Latinized as
Cassenius. On 26 July 1364, the eponymous
battle between the armies of
Pisa and
Florence was fought here. The event was later reproduced by
Michelangelo in painting, of which now preparatory drawings and a copy by Aristotile da Sangallo (also known as
Bastiano da Sangallo) exist. The city had in fact a strategical importance as a fortified stronghold on the main road connecting the two cities. ==Geography==
