Catherine 2 had put up a monument to Peter the Great in St. Petersburg. The 'Bronze Horseman' as Pushkin referred to it, has become an iconic symbol of that city. The sign on the stone reads "To Peter I from Catherine II". Of course Catherine was in no way related or descendant from Peter, so the monument had a political significance in establishing a feeling of continuity in the ruling dynasty.
Eugene do you want one? I have a spare.
I also have 2 copper medals, one is similar to the above token, and the other celebrates the transport of the rock that the horseman is mounted on. Apparently that alone was a "monumental" undertaking, and took a lot of effort and a lot of serfs.
