Its history is linked to thermal waters in the past and especially during Roman times, from which it keeps some interesting remains such as the Roman villa in Can Terrers which has been declared National Cultural Heritage. The town centre was built around a thermal spring, which has waters that boil at over 60ºC.
Its thermal waters have been used during centuries, however, it was at the beginning of the twentieth century when the holiday phenomenon caused high demand for this natural heritage and Catalan middle classes chose La Garriga as a destination.
