Impressive ice well in Fuendetodos, birthplace of Goya. One of ~1000 in Aragón, Catalonia, Valencia, Murcia Built during the Little Ice Age (C16-19th) they were big business in Eastern Spain. Ice wae collected over winter in sierras, stored and shipped to the cities until the early C20th when technology rendered them obsolete.

It goes without saying that climate change has rendered them ultra-obsolete. So little snow falls in these places in the heating 21st century.
