Milos island in Greece has been inhabited since the prehistoric times and was largely developed due to its sulfur mines. During the Bronze Era (2800-1100 BC), it became an important center in the Aegean Sea. Excavations from the ancient city of Phylakopi are today hosted in the Archaeological Museum of Milos and show a developed early settlement.
In the centuries that followed, Milos was invaded by the Mycenaeans and the Dorians and flourished in pottery. During the ancient times, Milos island was twice besieged by Athens as the locals decided to stay neutral in the Peloponnesian War.
The Roman times was again a flourishing period for the island, as shown by the Ancient Theatre excavated there. This is when the port of Milos became an important stop on the way from eastern to western Mediterranean Sea and this why Christianity arrived so early on the island. In fact, from as early as the 1st century AD, the local Christians were building catacombs to get away from the persecutions by the Romans. The impressive element is that the Catacombs of Milos, that are open to visit today, are the second largest catacombs in the world, following those of Rome.
In the Medieval Ages, Milos in Cyclades was conquered by the Venetians and then the Ottomans, while the coastal regions were frequently raided by pirates. Finally, in 1830, like all the Cyclades islands, Milos became part of the modern Greek State.
