Truro is a city in Cornwall, England, United Kingdom. It is the administrative centre, the most southerly and the only city in the county.
Truro's name is derived from the Cornish tri-veru meaning "three rivers". The city grew to be an important centre of trade thanks firstly to its port, but later because of its role as a stannary town for the mining industry. Today, Truro is the centre for administration, leisure and retail in Cornwall and has a population of 20,920. Its residents are known as Truronians.
The city is well-known for its cathedral (completed in 1910), as well as its cobbled streets, open spaces and many examples of Georgian architecture. It is also the location of the Royal Cornwall Museum, the Hall for Cornwall, Cornwall's Courts of Justice and Cornwall County Council's Old County Hall, a Grade II listed building.
