Abstract[EN] Lacustrine and travertine records from Laguna de Taravilla (Iberian Range, Guadalajara province, Spain, 40° 39’ N, 1° 59’ W, 1100 m a.sl.) have been analysed using sedimentological, mineralogical, geochemical and palynological techniques. A preliminary chronological framework is based on U/Th, 14C AMS, 210Pb and 137Cs dates. Phases of increased travertine growth occurred during the GlacialInterglacial transitions from isotope stage 6 to 5 and 2 to 1. Short lacustrine cores indicate a lake level and surface area increase after the XVth century, that can be correlated with the end of the Medieval Warm Period. Sandy facies related to flood events are more frequent during the interval ascribed to the Little Ice Age. The growth of littoral vegetation at the mouth of the inlet could have prevented more sandy sediments to reach the center of the lake during the last century.
