Actually, two, since this statue of Kaiser Wilhelm II in Cologne, Germany, is not far from a statue of his grandfather, Wilhelm I near the Hohenzollern (that’s their family name) Bridge.
While there are numbers of equestrian statues of I in various parts of Germany, this is only one of two surviving of II, all that’s left of 63 that were built while he ruled, through the end of World War I.
If it seems huge, it is: it stands 19 metres high.
