That’s the case with the Vittoriano. For most tourists is memorable; for most Romans is just akward.
The monument was built to celebrate king Vittorio Emanuele II after his death, and apparently the mindset was “throw it all in”. More than a monument is a complex of monuments that comemorate the king, the unknown soldier, the Italian virtues, and the Italian regions. Probably that’s why most people just call it “Altar of the Fatherland”, although those less enthusiastic about its anachronistic style have coined affectionate nicknames as “The Wedding Cake” and “The Typewriter”.
