Legrena

SS Oria was a Norwegian steamer that sank on 12 February 1944, causing the death of some 4,095 Italian prisoners of war, 21 Greeks and 15 Germans. It was one of the worst maritime disasters in history, and the worst maritime disaster caused by the sinking of a single ship in the Mediterranean Sea.

The Temple of Poseidon is an ancient Greek temple on Cape Sounion, Greece, dedicated to the god Poseidon. There is evidence of the establishment of sanctuaries on the cape from as early as the 11th century BC. Sounion's most prominent temples, the Temple of Athena and the Temple of Poseidon, are however not believed to have been built until about 700 BC, and their kouroi (freestanding Greek statues of young men) date from about one hundred years later. The material and size of the offerings at the Temple of Poseidon indicate that it was likely frequented by members of the elite and the aristocratic class. The Greeks considered Poseidon to be the "master of the sea". Given the importance to Athens of trade by sea and the significance of its navy in its creation and survival during the fifth century, Poseidon was of a particular relevance and value to the Athenians.

Cape Sounion (Modern Greek: Aκρωτήριο Σούνιο Akrotírio Soúnio [akroˈtirʝo ˈsuɲo]; Ancient Greek: Ἄκρον Σούνιον Άkron Soúnion, latinized Sunium; Venetian: Capo Colonne "Cape of Columns") is the promontory at the southernmost tip of the Attica peninsula, 8 kilometres (5.0 mi) south of the town of Lavrio (ancient Thoricus), and 69.5 km (43.1 miles) southeast of Athens in the Athens Riviera. It is part of Lavreotiki municipality, East Attica, Greece. Cape Sounion is noted for its Temple of Poseidon, one of the major monuments of the Golden Age of Athens. Its remains are perched on the headland, surrounded on three sides by the Aegean sea.

Atene (Greek: Ἀτήνη) was a coastal (paralia) deme of Attica, belonging to the Antiochis tribe (phyle), with three representatives in the Boule. It bordered Anaphlystus to the north and Amphitrope in the east, in what is now the southern part of Saronikos municipality. It had an area of about 20 km2, including the valleys of Charaka, Hagia Photini and Thimari as well as Gaidouronisi. The area had been mostly uninhabited prior to the 5th century BC. The first epigraphic mention of Atene dates to 432 BC. It prospered during the 5th to 4th centuries BC, with a dispersed settlement pattern, but was depopulated in the 3rd century BC, probably in the wake of the Chremonidean War.

Amphitrope (Greek: Ἀμφιτρόπη) was a minor coastal (paralia) deme of ancient Attica, belonging to the Antiochis tribe (phyle), with two representatives in the Boule. It was situated in the valley of Legrena, between mount Baphi to the west and mount Spitharopussi to the east, close to the modern settlement of Synterina (Συντερίνα, 37.73°N 23.99°E / 37.73; 23.99), neighboring the demes of Atene to the west, Sounion to the east and Thorikos to the north-east, on the border between the modern Saronikos and Lavreotiki municipalities. It was one of the smaller demes of the Mines of Laurion district, with eight or nine mines. According to Aeschines (Against Timarchus 101), the father of Timarchus had possessions in Amphitrope which he was forced to sell to pay to cover the expenses of the liturgy. The site of Amphitrope is tentatively located at Pousipelia Megalo Peuka.

Patroklos (Greek: Πάτροκλος) or Gaidouronisi (Γαϊδουρονήσι, "donkey island") is a small, private island located in the Saronic Gulf, Greece. It is situated about 65 km from Athens and 3 km from Sounion and is part of the Attica region. In ancient times, the island was known as Patroklou Charax (Πατρόκλου χάραξ, meaning "Camp of Patroclus") or Patroklou Nesos (Πατρόκλου νῆσος, meaning "Island of Patroclus"), after the Ptolemaic admiral Patroclus, who established a fortified base there during the Chremonidean War. In the late Middle Ages, the island was notorious as a haven for pirates. The Byzantine emperor John VIII Palaiologos was nearly captured by Catalan pirates in December 1437, when his ship sought shelter from a storm on the island during his journey to the Council of Ferrara. On 12 February 1944, SS Oria sank in a storm on the south east rocks of Patroklos island with 4,074 killed, mostly Italian military internees. It was also the island at the heart of the Israeli political scandal known as the "Greek island affair". The island is operated under Greek administration but is owned by the Prince Obolensky, Arnaud Henry Salas-Perez.

Besa (Ancient Greek: Βῆσα) was a deme of ancient Athens, situated in the mining district, midway between Anaphlystus and Thoricus, and 300 stadia from Athens main city. Xenophon recommended the erection of a fortress at Besa, which would thus connect the two fortresses situated respectively at Anaphlystus and Thoricus. The site of Besa is located near the modern Synterina.

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.

Its site is located near the modern Panormo.
