Trelion

Trelion is a hamlet in the TR2 postcode district of Cornwall, set within England’s South West. Small and understated by name, it offers a quiet base from which to appreciate the county’s deep-rooted industrial past. Cornwall’s mining story is never far away: elsewhere in the county, South Terras Mine—a disused uranium and radium workings near Grampound Road and St Stephen-in-Brannel—recalls earlier eras of extraction. Before its later focus on radioactive ores, South Terras produced tin, iron and ochre, and in 1996 it was designated a site of special scientific interest for the variety of unusual and rare minerals found there. For visitors drawn to geology, industrial heritage or simply the textured history of Cornwall’s settlements, Trelion’s location in TR2 places it within reach of those stories. The hamlet’s modest identity is part of its appeal, offering a quiet Cornish note amid a landscape shaped by centuries of mining and the mineral riches that continue to intrigue scientists and enthusiasts alike.
