THERE'S nothing worse than somebody watching you over your shoulder when you're trying to work, but sculptor Katherine Sullivan evidently got used to the feeling during her six-week stint as artist in residence at Chepstow Castle this summer.

She involved the many people who visited her tent to watch her at work in the work itself - and the amazing result is now on show at Chepstow Museum.

Inspired by the early medieval architecture of the castle and the clothes that its original inhabitants would have worn, Raglan-based Katherine's work also incorporates elements of the months she spent on site working on the piece.

She said: "I was helped in this quest by the large number of re-enactors who visited the castle during my stay, including 200 members of the Robin of Sherwood Convention on May 25.

"Among their members were Nancy and Kia, all the way from Boston, who shared very detailed knowledge of early medieval textile techniques with me.

"Early medieval clothing has little structure for a sculptor to plunder, but the Gothic Point, which is found in hats, shoes and sleeves and is echoed in the vaulted roofs, windows and door arches of the ruins, has provided me with the structural theme of my structure.

"The paths in the grounds of the castle are well-worn by visitors both past and present. All the visitors to my tent had their shoes photographed and these will be visible in the exhibition."

The photographs, drawings, and models which formed part of Katherine's working process are also on display at the museum.

The exhibition runs until September 22 at Chepstow Museum, Bridge Street, Chepstow. The museum is open from 10.30am to 5.30pm from Monday to Saturday, and from 2 to 5.30pm on Sundays.
