Considering the Corallo in La Spezia?

Big! by micas_pt
One thing that struck us about La Spezia was the size of the Naval Dockyard: it is huge!! When we drove past La Spezia heading for Portovenere we took a small road and drove along the naval dockyard for quite some distance. It spreads along the coast for some km, and it is obviously restricted to visitors. Looks like as it is of major importance in naval defense.
Finally we stopped at a higher point and were able to watch it from the distance. Also, from the opposite side of that road the view towards Portovenere is breathtaking!!
