Roof Finials

Marking or finishing the top end or corner of a gable, pinnacle or other such structure. Decorative in nature and traditionally carved from stone, these timber pieces will proudly adorn any structure.

Wiki: During the various dynasties in China, a finial was worn on the top of the hats civil or military officials wore during formal court ceremonies. The finial was changed to a knob for other daily usage (including semi-formal ceremonies).
