It is known that the name of Ca n'Abat comes from the fact that around the 17th or 18th century, an abbot of Montserrat who was very sensitive to the cold and had a hard time in winter in the steep monastery exposed to all the elements, spent long periods in a manor house in Castellví de Rosanes, near the Anoia river.
Years later, Josep Manso i Solà (Borredà, 1785-Madrid, 1863), a captain in the War of Independence who later rose to the rank of brigadier general and was governor of the Ciutadella in Barcelona, was entrusted with the southern defence of Barcelona, and a garrison was installed in Ca n'Abat whose main task was to ensure that, in the event of war, the enemy did not cross the Llobregat river. At that time, the river could only be crossed by the Pont del Diable in Martorell and by the barge of Sant Andreu de la Barca (hence the name of the town). In 1844, Josep Manso received the title of Count of Llobregat, ending his military career as Captain General of Aragon, then of Valencia and finally of New Castile.
In 1855, Ca n'Abat underwent extensive remodelling and extension by the new owner, the Marchioness of Gelida. The lady was known in the area for organising great festivities and the most famous, as illustrated by an engraving of the time, consisted of diverting water from the Anoia River, creating an artificial lake on the grounds of the mansion and celebrating a Venetian carnival with gondolas sailing through the waters.
Today, the Ca n'Abat estate is divided into several estates and has different owners: the main house, the wine cellars, the vineyards and the old stables with the annex buildings.
