Kannelure - a vertical groove (groove) in columns or balusters. Kannelure creates a relief surface, with fixed parameters of depressions. Depending on the size of the columns, different flutes of different diameters are used. Frequently used cannulated columns from a long time ago. Now also used as decoration by columns of interiors, and also exteriors.
