"Earth has not anything to show more fair," wrote the poet William Wordsworth about... ...what?

Wordsworth's poem is entitled "Upon Westminster Bridge" and it runs:

Earth has not anything to show more fair:

Dull would he be of soul who could pass by

A sight so touching in its majesty:

This City now doth like a garment wear

The beauty of the morning; silent, bare,

Ships, towers, domes, theatres, and temples lie

Open unto the fields, and to the sky;

All bright and glittering in the smokeless air.

Never did sun more beautifully steep

In his first splendour valley, rock, or hill;

Ne'er saw I, never felt, a calm so deep!

The river glideth at his own sweet will:

Dear God! the very houses seem asleep;

And all that mighty heart is lying still!
