Tower clock of Santa Marina del Rey Monument · Santa Marina del Rey, El Páramo, León Image of Santa Marina del Rey, not of the place itself. A mechanism dated 1599 and signed by Antonio Villafranca, a locksmith of the city of León. It has survived four centuries and until very recently was still driven by weights, just as on the day it was installed.
