In the lush, green countryside of North Cornwall, near Launceston, is the small village of South Petherwin with an ornate tall-towered church dedicated to St Paternus and built from stone sourced at the local Polyphant quarry. Polyphant stone was also much used in the construction of Truro Cathedral. In the 1800s this area was also one of the many in north Cornwall to quarry slate.
Trekelland Bridge is a beautiful stone bridge over the nearby River Inney. Its pub, the Winds of Change, serves good food and ales. Just across the A30 is Trethorne Leisure centre which offers "45,000 sq. ft. of undercover entertainment" for all the family, including golf, bowling and farm animals. Not far from here, another good family day out can be had at Hidden Valley Discovery Park complete with model steam railway and treasure hunts in a pretty countryside setting.
