Next to the popular Fountain of the Mingo, already outside the old town and in the direction of the old orchards of the stream, stands a circular tower known by the Sadurninans as the “Carlin Tower”. The name refers to the episodes experienced during the Carline Wars of the 19th century, when the Anoia line was the site of skirmishes between factions. According to tradition, the structure — possibly later converted into a water reservoir — served as a watchtower to monitor the arrival of Carline ships that took advantage of the dense network of rural roads.
The tower, made of masonry joined with lime and topped by a simple exposed brick crown, still retains narrow spitters that reveal its original defensive function. The interior, now inaccessible for safety reasons, shows the remains of a spiral staircase and a small metal tank that was added at the beginning of the 20th century to regulate the water supply from the nearby spring.
Despite being a modest element, the “pug” has a strong symbolic load: schoolchildren stop there during excursions to discover the neighborhood and the guided tour “Discover the anecdotal Sant Sadurní” tells stories of sieges, ambushes and popular heroics. The City Council has a consolidation project on the table to stop the rising humidity and better signal the environment, but at the moment the tower can only be seen from the outside, integrated in a shaded space that many take advantage of to take a bite while listening to the constant chirping of the Mingo Fountain.
