It has been estimated that in the 10th century Córdoba was the most populous city in the world, and under the rule of Caliph Al Hakam II it had also become a centre for education under its Islamic rulers. Al Hakam II opened many libraries on top of the many medical schools and universities which existed at this time. Such universities contributed towards developments in mathematics and astronomy. Today it is a moderately sized modern city; its population in 2011 was about 330,000. The historic centre was named a UNESCO World Heritage Site.
