The name of the town, part of the Arlanza region, comes from the Arabic word "maza" (a word for "maza") and "rais," meaning "meadow" or "field." In addition to being part of the Wool Route and the Camino del Cid's route to Exile, it is very common to play the dulzaina, a typical instrument of the area. The town attracts tourists with its prehistoric dolmen of Cubillejo de Lara, the Roman archaeological site of the Terra Sigillata pottery factory in Valdarcos, and the factory and works of art in the parish church of San Martín Obispo.
