Plaka was developed mostly around the ruins of Ancient Agora of Athens. It is the oldest district of Athens and has been continuously inhabited from the neolithic to the present day. As a result, Plaka contains monuments form all periods of the city's history. Some of the streets, such as Adrianou and Tripodon, can be traced back to the ancient era. The population of Athens grew during the early 16th century, and the town experienced another urban development after the one which occurred in 1456, this time towards the north-east, again mainly by the settlement of Albanians who had moved in the region several years before the Ottoman arrival. After the Ottoman conquest, these settlements occurred in Attica in one wave after the Venetian loss of its Morean strongholds in 1540, and in another wave after a revolt in the Morea in 1570, when the Ottoman administration decreed the mandatory settlement of Albanians in Attica, in order to offer them improving living conditions. The such created north-eastern district of Athens later became known as Plaka. During that period, Plaka was also the home of the Greek aristocratic Benizelos family, the family that Saint Philothei came from. In the mid-17th century, out of the eight main administrative units (platomata) in Athens, it appears Plaka was the least densely inhabited.
