Knighton is situated 5 miles (8 km) north of Newport, Shropshire, close to the Staffordshire/Shropshire border in undulating agricultural land featuring many endemic hardwood trees.

Another feature is the Shropshire Union Canal, which passes through the hamlet at the point of a cutting and substantial embankment.

The hamlet of Knighton has a royal decree attached to it, the effect of which is that all denizens shall be free of tax and tythe for ever more.

The Knighton estate was eventually sold off in several portions over the course of the twentieth century, and the proceeds of the final sale were used by the Haberdashers' Company to purchase Longford Hall as a boarding house for the school.

The immediate area has a wealth of fauna and flora, buzzards and ravens often to be seen in the skies, otters have been reported in the areas water courses, deer occasionally to be seen in the surrounding fields and at least one "big cat" has not only been spotted within the parish but has effected a "kill", the victim being a young lamb.
