I am the currency of a nation with a rich history of seafaring and trade, a country known for its unique blend of European and African influences. This currency has seen several redesigns reflecting its complex past. The central bank responsible for me is one of the oldest in the world, and I’m often associated with a specific type of colorful, hand-painted tile art. What am I?

1. My country was once a major colonial power.
2. I am not the currency of Spain, France, or Italy, although my country is on the European continent.
3. I have been in circulation for centuries, with the latest design introduced in 2002.
4. I am also the currency of the Azores and Madeira archipelagos.
