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.

Its site is located near the modern Panormo.

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 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.

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.

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.

Lavreotiki is a municipality at the southeasternnmost tip of the Attica peninsula in the Greek regional unit of East Attica. Its municipal seat is the town of Laurium (Lavrio). It is historically important as a significant ancient mining district, most notably in the villages of Laurium and Thorikos on the southeastern seaboard during the 6th, 5th, and 4th centuries BCE. As such it financed the wealth of Athens and the emergence of the Athenian Empire through the slave-powered mining efforts for silver and lead, beginning with the discovery of 2 deep-vein mining efforts during the 480's. Prior to that development, which at Themistocles urging in 483 BC led to the expansion of the Athenian fleet to 200 ships, only surface-mining was deployed as a technique for harvesting silver. More than 250 ore washeries have been identified by archaeologists and geologists in the district.
