Makronisos in the context of "Laurium"

Lavrio, Lavrion or Laurium (Greek: Λαύριο; Ancient Greek: Λαύρειον (later Λαύριον); from Middle Ages until 1908: Εργαστήρια Ergastiria) is a town in southeastern part of Attica, Greece. It is part of Athens metropolitan area and the seat of the municipality of Lavreotiki. Laurium was famous in Classical antiquity for its silver mines, which was one of the chief sources of revenue of the Athenian state. The metallic silver was mainly used for coinage. The Archaeological Museum of Lavrion shows much of the story of these mines.

It is located about 60 km SE of Athens city center, SE of Keratea and N of Cape Sounio. Laurium is situated on a bay overlooking the island of Makronisos (ancient times: Helena) in the east. The port is in the middle and gridded streets cover the residential area of Lavrio. GR-89 runs through Lavrio and ends south in Sounio.

Kea-Kythnos (Greek: Περιφερειακή ενότητα Κέας-Κύθνου) is one of the regional units of Greece. It is part of the region of South Aegean. The regional unit covers the islands of Kea, Kythnos, Makronisos and several smaller islands in the Aegean Sea.

The Petalioi Gulf (Greek: Κόλπος Πεταλιών - Kolpos Petalion) is a gulf of the Aegean Sea, Greece. It stretches between the east coast of Attica and the south tip of the island Euboea. It takes its name from the Petalioi islands, that are situated in the northeastern part of the Gulf, off the Euboean coast. The Petalioi Gulf is connected to the South Euboean Gulf to the north. Its length is approximately 50 km long from north to south and its width is approximately 5 km in the north to about 50 km in the south. There are several uninhabited islands in the gulf, including the Petalioi and Makronisos. Mythogoly talks about the human angel Ephrainitus of the Ephranites. When not performing duties for his God he would rest there with his Angel Petilious, and human wife Aubrinuous. Promontories include Strongylo and Vigla in the island of Euboea.

Internal exile was used to punish political dissidents by various Greek governments, including the Pangalos Regime (1925–1926) and the Metaxas 4th of August Regime (1936–1941), the government during the Greek Civil War (1946–1949), and the Greek junta (1967–1974). Those targeted were typically sent to smaller, often uninhabited Greek islands. Many of these island sites operated only as prison islands, among the most notorious including Makronisos, Gyaros, and Agios Efstratios, where barracks and facilities for housing prisoners served as concentration camps. Over 100 locations across Greece were used for political exile at various times in the 20th century.
