Alexandria became the second capital of Egypt around 332 BC when it was conquered and named by Alexander the Great.  The ancient city of Alexandria was discovered underwater in the Mediterranean Sea and archeologists began bringing artifacts up around 1994.  What makes this particular city so interesting is the mix of ancient Egyptian and ancient Roman architecture.  Apparently, Alexander the Great, knowing Egypt was strongly connected to its faith, adopted the religion of the ancient Egyptians (you can even see hieroglyphics of Alexander in traditional Egyptian attire giving offerings to the gods in Luxor Temple), and so we get this awesome combination of Roman amphitheaters and corinthian columns next to sphinxes and hieroglyphics.

We visited three main sites in Alexandria (which sits on the edge of the Mediterranean Sea across from Italy and Greece): the Roman amphitheater, circa 332 BC; the Citadel, circa 1477 AD; and the Catacombs, circa 200 AD.
