The five euro note is the smallest at 120 by 62 millimetres (4.7 in × 2.4 in) with a grey colour scheme.[1] All bank notes depict bridges, arches or doorways in a different historical European style; the five euro note shows the Classical era (up to the fifth century).[26] Although Robert Kalina's original designs were intended to show real monuments, for political reasons the bridge and art are merely hypothetical examples of the architectural era.[27]
