Old County Hall is a municipal facility at Station Road in Truro, Cornwall.

[1] In the 19th century the Shire Hall in Bodmin was well established as the venue for dispensing justice in the county.

[1] The design involved a symmetrical main frontage with eleven bays facing onto Station Road with the end bays slightly projected forwards; the central section, which also slightly projected forward, featured a bow-shaped porch with Tuscan order columns; there was a round headed window on the first floor and a pediment above; there was a cupola with a weather vane at roof level.

[6] The building, which became increasing blackened with soot from the local factory chimneys, was extended in 1925 and again in 1939.

[8] The Board of Inquiry into the loss of the pleasure cruiser MV Darlwyne, which resulted in the deaths of thirty-one people (two crew and twenty-nine passengers including eight children), was held in the Old County Hall in December 1966.
