Marrecs de Salt, Human tower group in Salt, Spain

Marrecs de Salt is a colla castellera founded on 8 November 1995 in Salt, Girona, and registered on 1 April 1996. Its members wear blue shirts, a colour chosen for the river Ter. The group's best tower is the 3 de 9 amb folre, first completed on 23 July 2017 during the Sant Jaume festivities in Salt.

The group was established in 1995 after members attended performances by other tower-building teams, making their debut in January 1996. This founding occurred during a period of growing interest in reviving traditional Catalan practices.

The group's name comes from a dialect word for "boy", popularised by the Xiquets de Valls; the blue shirt stands for the river Ter. Each September the Colles de l'Eix meeting rotates between Salt, Manresa, Lleida and Vic, ending with a shared 4 de 7 built from one row of each group, mixing blue, striped blue, burgundy and orange shirts.

The group meets weekly at their headquarters in Naus Guixeres for training sessions where experienced members teach newcomers the techniques and movements. Visitors can watch or participate in public performances during local festivals throughout the year.

The group's shirt is blue because it stands for the river Ter, which flows through both Salt and Girona. The name itself is a dialect synonym of the word for "boy", a term popularised by the Xiquets de Valls and already used in 1985 by the short-lived Marrecs del Catllar.
