Answer: The answer is that effect of Muslim culture is seen most clearly in Spain, under Islamic rule.
Step-by-step explanation: If we talk about the linguistic influence we know that Spanish has many words of Arabic origin and it is because of the Arab-Spain relation even before its conquest. Taking entertainment in consideration we see that Spanish music is also influenced by the historic Muslim presence in the peninsula. The instruments and melodies they brought to the region would later give way to the guitar and flamenco. Even the name of the places and many other Arabic culture's foot prints can be seen in Spain.
