At Pennington a tympanum was discovered with runic letters. A tympanum is an architectural term for a semi-circular or triangular shaped surface over an entrance. A rune is a letter of an alphabet and these were used to write in Germanic languages, including Scandinavian ones. The Pennington tympanum probably came from the church and is believed to be late Scandinavian.
You might be able to read this extract from the inscription on the tympanum. Kirk is fairly clear (meaning church). This word is still widely used in Scotland today.
There is another rune-inscribed stone (at Urswick) but it is believed to be of Anglo-Saxon date and not Viking.
