I was preparing a few slides for teaching History of Medicine when I decided to read up further on Seville. Seville was an Arabic stronghold by the Arabic name of Ishbiliyah. This is mentioned in the Wikipedia pages on Seville.
Another note I stumbled upon was oranges. Navel oranges are known to be sweet. So are Sunkist oranges. But the oranges in Seville are bitter and are used to make marmalade. They were planted or brought in to Seville at the time the mosque was built. The mosque is no longer there but a cathedral was built in its place and the minaret was turned into a bell tower but the ramp remained as the muazzin then had used a horse to ride up to the top.
