CAMBORNE, a market town in the Camborne parliamentary division of
Cornwall, England, on the Great Western railway, 13 m. E.N.E. of
Penzance. Pop. of urban district (1901), 14,726. It lies on the
northward slope of the central elevation of the county, and is in the
neighbourhood of some of the most productive tin and copper mines. These

The parish church of St Martin contains several monuments and an ancient
stone altar bearing a Latin inscription. There are science and art and
