Pine of the Chain Nature · Cercedilla, Cuenca del Guadarrama, Madrid Image of Cercedilla, not of the place itself. A Scots pine almost two hundred years old, declared a notable tree of the Region of Madrid: in 1924 the publisher Nicolás María Urgoiti bought the tree and girdled it with a chain bearing the legend "To his dear memory 1840-1924", in memory of his father.
