There are so many things to see in Cerdanyola del Vallés, a town with a fascinating legacy covering different eras, that we recommend you dedicate a whole day to it. You could, for example, start the day by visiting the Poblat Íber de Ca n’Oliver, an archeological site of a settlement once inhabited by a Laietani tribe between the 6th and 1st centuries A.D. The site, which occupies more than 6,000m2, is located on a hill in the Collserola mountain range, and houses a museum and three replica buildings – two houses and a workshop – where you can learn about the daily life of the Iberians.
After this you could hop into an imaginary time machine and travel to the time when Cerdanyola became an important summer holiday destination, at the beginning of the 20th century, and visit the modernista building Can Domènech. Built by Gaietà Buïgas, the building was once home to the Teatre Casino, and was later privately owned. Since 2009 it's been the headquarters of the Museu d'Art de Cerdanyola, displaying works by a wealth of artists linked to the city, including the stained glass piece 'Les Dames de Cerdanyola', (The Ladies of Cerdonyola), which is considered a masterpiece of the modernisme art movement.
Perhaps you’ll then whizz back, in your machine, to the medieval period of Cerdanyola, and take a look at the castle of Sant Marçal, another national heritage site. Though the castle was refurbished in 1895 by Gaietà Buïgas, it retains its historic 12th century appearance. In the outskirts of the Vall de les Feixes (in the Collserola mountain range), you’ll find the 12th century Roman parish church of Sant Iscle and Santa Victòria de les Feixes, as well as the 14th century baroque hermitage of Santa Maria de las Feixes. These are just a few of the ‘must sees’ of Cerdanyola.
