Mas d’en Guasch oil is very closely linked to San Mateo, one of the largest and best preserved towns of the Maestrazgo region. Its monumental legacy is impressive, and the historical-artistic grouping of its medieval town centre was declared an Asset of Cultural Interest by the Generalitat Valenciana (Valencian Government) in 2002. Among these monuments you will find the Arciprestal Church, Saint Peter’s Church and the Las Agustinas Convent and Church, as well as the Our Lady of the Angels chapel. Also of interest are the Town Hall, the Borrull, Cortes de Aragón and Marquis of Villores palaces, the Gothic Furnace and the Walls. The region’s gastronomy and local festivals are also key attractions.Mas d’en Guasch oil is very closely linked to San Mateo, one of the largest and best preserved towns of the Maestrazgo region.
