	016 of 182. This plaque on the ground directly north of the Post Office serves as the symbolic center of Spain. Kilómetro cero (kilometer zero) marks the center of the Spanish road system.....the starting point for the 6 main highways in Spain. (The plaque that marks this point was turned around 180 degrees in 2002 because the map of Spain depicted on it was upside-down in relation to reality.)
