pantechnicon: [19] The original Pantechnicon was a huge complex of warehouses, wine vaults, and other storage facilities in Motcomb Street, in London’s Belgravia. Built in 1830 and supposed to be fireproof, it was almost totally destroyed by fire in 1874. It seems originally to have been intended to be a bazaar, and its name was coined from the prefix pan- ‘all’ and Greek tekhnikón, the neuter form of tekhnikós ‘artistic’, denoting that all sorts of manufactured wares were to be bought there.

But it was its role as a furniture repository that brought it into the general language. Removal vans taking furniture there came to be known as pantechnicon vans, and by the 1890s pantechnicon was a generic term for ‘removal vans’.
