Composed upon Westminister Bridge- Analysis- 

Earth has not any thing 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.

   In the first three line of the octave, the poet is looking at a sight that according to him is the fairest and most beautiful sight on Earth. Anyone who passes by without looking at the sight possesses a very dull soul. The sight is touching and majestic in nature.
In the fourth line, the speaker finally reveals his sight to the readers which is the City that looks like wearing a garment. (London is probably covered in white snow.)
The speaker moves on to appreciate the beauty of the morning where all the hustle-bustle and ruckus of London is silent - the ships, towers, theatres, domes, and temples. They all lie silently on the field and glittering in the smokeless morning air. (Since the factories haven't started production yet.)

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!

 In the first three lines sestet of the poem, the speaker says that he has never felt, never seen such a calmness. The valleys, rocks, hills, and even the sun look beautiful and splendid. The river (The Thames) is gliding at its own sweet will. 

Every house appears so still as everyone is still sleeping and the heart of the city has stopped and lying still. 

The poet paints a very vivid picture of London from Westminster Bridge in the early morning. The biggest commercial hub and the city of industrialization are lying asleep and the poet is awestruck by its beauty.
