Athens, is the capital city of Greece with a metropolitan population of 3.7 million inhabitants (2020). It is in many ways the birthplace of Classical Greece, and therefore of Western civilization.

The first pre-historic settlements were constructed in 3000 BC around the hill of Acropolis. According to legend the King of Athens, Theseus, unified the ten tribes of early Athens into one kingdom in around 1230 BC. This process of synoikismos – bringing together in one home – created the largest and wealthiest state on the Greek mainland, but it also created a larger class of people excluded from political life by the nobility.

Athens was just a small provincial city when it was chosen in the 1830s to serve as the national capital of the modern Greek State. Although it had a prestigious past, the city's political, economic and cultural importance had declined over the centuries, leaving behind only its classical ruins as a reminder of better times. With the decision to move the national capital from Nafplio to Athens, architects and city planners were hired to build a new city next to the classical ruins, with grand neoclassical homes and public buildings, large city squares, green spaces, and wide avenues, making a conscious, decisive turn from the city's Ottoman past. The city regained its importance in Greek civilization, and by 1900 had evolved into a very attractive cosmopolitan city, with abundant neoclassical architecture harking to the nation's past.
