Truro gets its name from the old Cornish word ‘tri-veru’, meaning three rivers, which also appears in 13th-century documents as try-weru, trywru and tryurw. The rivers in question are the Kenwyn, Allen and a little stream under Tregolls Road. The Kenwyn passes alongside Lemon Quay. The river was covered over for car-parking in the 1920s and 30s. This area is now an Italian-style piazza.
