It's actually not a palace but a 16the century fortress.
It does look lame/unimpressive but it has history: it was once (maybe still?) owned by the Medici family (the Mecicis are arguably the most important elite family in Italy - they ruled Florence. And their descendants still exist and have royalty titles even tho Italy is not a monarchy.
Those photos look more impressive than the shots from earlier. Seriously the grass looked near dead and everything.
