In the Wikipedia - Queluz National Palace
...Comparisons with the far larger and more Baroque Versailles are unwarranted: Versailles is referred to as having "an aura of majesty" and it was built and dedicated to exhibit in stone "all the glories of France," whereas the far smaller palace at Queluz has been described as "exquisite rather than magnificent" and looking like "a very expensive birthday cake".
