The Gardunha mountain range (Serra da Gardunha), so called by the Moors (Gardunha or Guardunha meaning refuge), is located in central Portugal, in Centro Region, beyond the Serra da Estrela range, giving way to an extensive plain called Cova da Beira. It was covered with vineyards in the time of King Dinis, who reigned in the 13th and 14th centuries. But the sovereign decided to pull them up and replace them with chestnut trees all over the Alcambar valley.
