Why would Spain have both roman aqueducts and mulslim mosques?

Spain's diverse architectural heritage reflects its complex history of conquest and cultural exchange. Roman aqueducts were built during the Roman Empire, showcasing advanced engineering to supply water to cities. Following the fall of the Roman Empire, the Moors invaded and ruled much of Spain from the 8th to the 15th centuries, leading to the construction of impressive mosques that incorporated Islamic architectural styles. This blend of Roman and Moorish influences highlights the country's rich tapestry of civilizations over centuries.
