London is the primary setting of the poem. While the city itself is not named in the text, the title implies that the speaker is describing an experience they had on Westminster Bridge, a famous bridge in London that crosses the River Thames. London is described mainly based on its physical features. For example, the speaker references its “ships, towers, domes, theatres, and temples,” as well as the “smokeless air” of the city in the morning (6, 8). In the twelfth line the describe the river running under the bridge, through the heart of the city, and in the following line the rows of houses along the river. The speaker spends most of the poem celebrating the majesty of the city before the day has begun. They claim its beauty is equal to that of anything in nature.
