Subject-verb inversion after place adverbials
When an adverb or an adverbial expression of place comes in the initial position (at the beginning of the sentence), the subject and verb are inverted:
Down the hill
rolled the children
.
Round the corner
was a nice café
.
This is a rhetorical device used mainly in formal and literary styles; however, it may also occur in everyday conversation:
Here
comes the bus
.
There
goes Sally
.
Here
's my number
.
But if the subject is a personal pronoun, there is no inversion:
Here
it comes
.
There
she goes
.
Here
it is
.
