as Gegants (giants), Dracs (fire-breathing dragons), and Mulasses (demonic Mules), and the construction of towering human castles (castell). Other festes celebrated in Vilanova include Tots Sants (November 1), Nadal (December 25), Cap d'Any (January 1), els Tres Tombs (January 17), la Diada de Sant Jordi (April 23), Nit de Sant Joan (St John's Night) and Sant Pere (St Peter's Day). Of international importance is the "Festival Internacional de Música Popular Tradicional", Vilanova International World Music Festival, which has been held since 1981 and is the oldest world music festival in Spain. Vilanova has a museum, founded by the Catalan poet, historian and diplomat, Víctor Balaguer (1824–1901), the Biblioteca Museu Víctor Balaguer, which contains collections of Roman, Egyptian and prehistoric antiquities, as well as paintings, engravings, sculptures, coins and a large library. Vilanova also has a railway museum, the Museu del Ferrocarril de Vilanova i la Geltrú which contains one of the largest collections of historic steam engines in the world.

Other local innovations include glòries, elaborate confections of meringue presented during carnaval that may be a dying tradition, and the Mig-Mig, a refreshing summer drink invented at the gelateria Cal Llorens, is a fifty-fifty blend of orxata de xufa made from tigernuts and granissat de llimona or pulverized ice with lemon syrup. Folklore Tradition maintains that Vila Nova (the new town) was founded by people fleeing the abuses of the feudal lord of the castle la Geltrú, particularly his exercise of the Droit du seigneur or jus primae noctis but there is no evidence that this is the case. Other traditions recount conflicts with invading Moors, the coming of the railroad, the inaccessible tunnels beneath the city and stories of a youth confounded by the reflection of the full moon in the water from which Vilanovins receive the nickname llunàtics (lunatics), in reference to a supposed mercurial quality of unpredictable emotions. Rather than a static tradition, folklore and festa in Vilanova are often used as a public way to respond to current events from immigration to national politics or to
