Relevant Context 

The River Avon, renowned for its wooded cliffs and suspension bridge, flows across the United Kingdom, enriching its soil and providing spectacular views. For instance, where the Avon flows below Bristol, the river has formed a limestone ridge that attracts many tourists from across the globe. But perhaps most iconically, the Avon River flows through the — supposed — birthplace of none other than Sir William Shakespeare. 

Ultimately, the River converges with the River Severn estuary at the ocean port of Bristol, Avonmouth. 

From the Text 

In Anna Barbauld’s “Eighteen Hundred and Eleven, a Poem,” the River Avon is only mentioned once (see line 141). In the poem, the allusion to the Avon functions largely to conjure imagery within the reader in a geographically considerate manner.
