St Peter's Square, Vatican City

...even so this
Outshining and o'erwhelming edifice
Fools our fond gaze, and greatest of the great,
Defies at first our Nature's littleness,
Till, growing with its growth, we thus dilate
Our spirits to the size of what they contemplate.

Byron, Childe Harold, IV 158, in The Complete Poetical Works II, p.177
