In Manresa, every February 21st is celebrated the Festival of Light  " La Llum" (as popularly known), which is full of values ??and recognized in 2009 as one of the 10 treasures of Intangible Cultural Heritage of Catalonia and Andorra.

Water and light are the symbols of this feast, which recalls the miracle by which, in 1345, a mysterious light came from Montserrat and got in the church of "El Carme". This fact resolved the conflict that had stopped the construction of the "Sèquia" (canal of irrigation) in Manresa.

- The "Transèquia" (a popular walking of 26 km. around the "Sèquia" channel of irrigation).

It also includes other events organized by various organizations and cultural entitis of the city related with the symbols of the festival, the medieval theme and the spirit of Manresa.
