Abstract
This paper proposed the constituent model for the arrangement of coastal structures in a fishery harbour. The model consists of the arcs of circle and ellipse and the line segment. In order to determine the aesthetic measure for the whole fishery harbour, the popularity of the constituent for coastal structures was evaluated by a questionnaire survey. The symmetrical elements impress us favorably. The curved shape is favorable. The rectangular structures, which are mainly shaped by means of right angles and line segments without symmetry, are common in Japan but artificially impressed.
