Column at St Mark's Square in Venice
A column in architecture is a vertical element that transmits the weight of the structure above to the structure below. Columns can be either a single piece or several pieces put together. Columns are frequently used to support beams or arches on which the upper parts of walls or ceilings rest.
[edit] History
Stone columns were already used in the architecture of ancient Egypt as early as 2600 BC.
