Originally built in the 19th century to vent smoke from steam boilers, these brick structures were designed by prominent engineers such as Narcís Nunell and Arnau Izard. Today, the Grau SA chimney stands as the tallest at 52.47 meters, while the Vapor Codina remains the oldest surviving example, dating back to 1880.

Beyond their industrial history, these chimneys have become artistic symbols. The landmark exhibition Ara, Sabadell featured eighty artists, including Javier Mariscal, who reimagined these structures as sculptures, ensuring that the city's industrial silhouette remains a central part of its modern cultural identity.
