As was customary throughout all history of our civilisation, large cities of high strategic importance were built along large rivers. Such location helped (or rather allowed) for large-scale trade and made defending and developing the nearby areas easier. Madrid is certainly one such city, being the capital of Spain for many years now, even if you’re more familiar with Barcelona when it comes to Spanish cities. As such, when going to Madrid, what river can you expect there? Which river flows through Madrid?
