_Er, hier_, and _daar_ can refer to a location. If they do, they translate to 'here' and 'there'.

Hij heeft | er | vandaag | niemand | gezien
He has not seen anyone there today.
In the above sentence, the emphasis is on the fact that the subject has not seen anyone today. The word 'there' is unstressed. Note that even in an unstressed form, it is also perfectly correct to use _hier_ or _daar._ It is just more common to use _er_ here.
