Rain chain

Rain chains (Japanese: 鎖樋, kusari-toi or kusari-doi,[1] literally "chain-gutter") are alternatives to a downspout.

Their purpose is largely decorative, to make a water feature out of the transport of rainwater from the guttering downwards to a drain or to a storage container.

Nordic vernacular architecture often used a simple stick as a rainwater guide, in similar fashion.

They have also been used in the Modernist era, to juxtapose metal chains with a concrete or Portland stone facade.

They are often seen in cup-shape, link and loop style, as well as decorative.
