Once the #Almohad left Iberia in 1228, the #Nasrid dynasty rose in what is now southern #Spain. The #EmirateOfGranada held out until #ThisDayInHistory in 1492, for most of that time the only peninsular #Muslim emirate. Its conquest by #Castile and #Aragon ended the #Reconquista.
Historically,,city of #Sevilla was strongly walled as a defense. There're some remains and one is #Macarena wall.
#DiputaciónDeSevilla is claiming that #JuliusCaesar built that and makes a fool of itself by changing entire history of #Sevilla
It was not so.
Macarena wall was built by #Almoravids, a sect of fanatical #Muslims who invaded Iberian Peninsula.although its barbican is #Almohad, sect number two also fanatical that also invaded Iberian Peninsula
It's worth seeing if u are in #Sevilla.

Thought-provoking: the #Astronomy knowledge and technology refined and developed by #Muslims during the #Almohad and #Nazarid reigns in #Andalucia was critical in the success of the #Spanish armada in colonizing the western hemisphere.

Below are pictures of nautical navigation instruments used by Spanish sailors. These tools were made after #Muslims were expelled from #Spain (starting in 1492 CE).

#Astronomy related instruments, refined and developed by #Muslim scholar-craftsmen during the #Almohad and #Nazarid eras in #Andalucia, are on display now at the Cuarto Real in #Granada .

Some of the knowledge and technology was a borrow from the Greek and Phoenician worlds, but the Muslim contribution to what we now know as astronomy is staggering in scope.

These are mostly reproductions: most of the originals have found their way into northern European museums.
