The palace impresses first with its early date of 1430.
It is a dramatic advance in concept, style and spaciousness compared to all preceding European palaces. It has been standing almost six centuries yet we find it pleasing and rhythmic, with no inferiority of design or proportion.
It has become such a timeless classic that it would not surprise one to see today a similar facade in New York or Chicago.
Compare it to any other structure built earlier, and it will be realized that this handsome residence, built by private citizens, was superior even to the palaces of kings at that time in England, France, or Germany.
