El Hierro the Meridian Island was once the end of the known world

El Hierro is the smallest of the Canary Islands
El Hierro is the most southerly and the smallest of the seven Canary Islands, which are located of the coast of North Africa and count as parts of Spain. El Hierro is probably the least well-known, and in fact, very long ago, it was considered the end of the known world for Europeans.
It's name is said to come from a Guanche word "Hero" that got transformed into "Hierro," which means the metal iron in Spanish. It is also thought that "Hero" as a Guanche term, or more technically a word used by the Bimbaches, which was the name for the Guanches that lived there, meant "cistern." This was because having no natural water sources on the islands apart from rain and mist, the people collected their water from the trees which condense it in the pine and laurisilva cloud forests just like happens still on the Tenerife, La Palma and Gran Canaria where these forests help pull in moisture from the clouds that form around the mountains.
El Hierro like its neighbouring Spanish islands is volcanic and has several microclimates and different types of countryside with mountainous areas, pine forests, grasslands, scrub and drier rocky parts. El Hierro also has many caves. Its crystal clear waters and abundant marine life have made it very popular with divers and there are many diving centres on the island.
Amongst crops grown on the island are grapes and pineapples. El Hierro has plenty of farms and a more old-fashioned style of farming
