El Hierro - "Isla de Meridiano"
In 1634 the zero meridian was established on El Hierro, when El Hierro was the end of the known world. In 1884 as a consequence of the International Meridian Conference in Washington D.C. it moved to Greenwich (although Paris did not recognize it for a further 27 years). The old zero meridian does not seem to be widely known or celebrated, a guide book told us we could get a certificate to show we had been there, but there didn't seem to be a representative of the government on hand to hand them out! In fact most maps do not even show where the monument is and an all terrain vehicle is needed to reach it.
