The Port of Piraeus (Greek: Λιμάνι του Πειραιά) is the chief sea port of Athens, located on the Saronic Gulf on the western coasts of the Aegean Sea, the largest port in Greece and one of the largest in Europe.
The Chinese state-owned COSCO Shipping operates the port.
Salamis (/ˈsæləmɪs/ SAL-ə-miss; Ancient Greek and Katharevousa: Σαλαμίς, romanized: Salamís) or Salamina (Modern Greek: Σαλαμίνα, romanized: Salamína) is the largest Greek island in the Saronic Gulf, about two kilometres (one nautical mile) from the coast of Athens' port of Piraeus and about 16 km (8+1⁄2 nmi) west of Athens center.
The chief city, Salamina, lies in the west-facing core of the crescent on Salamis Bay, which opens into the Saronic Gulf. On the eastern side of the island its main port, Paloukia, connects the island with Perama in the western part of Athens urban area through a frequent ferry line and is the second largest port in Greece in terms of passengers, after the port of Piraeus.
Perama (Greek: Πέραμα) is a coastal town and a suburb of Piraeus and belongs to the Piraeus regional unit and is the southwestern limit of Athens urban area. It lies on the southwest edge of the Aegaleo mountains, on the Saronic Gulf coast. It is 8 km northwest of Piraeus, and 14 km west of the center of Athens. The municipality has an area of 14.729 km. It forms the western terminus of the Port of Piraeus, and there is also a passenger port that provides ferry services to Salamis Island.
The name Perama comes from the Greek word "perasma" which means "passage". Perama has a secondary soccer team named Peramaikos. The Battle of Salamis which took place in 480BC was located between the Salamis island and the mainland, part of which included Perama.
Line 3 of the Athens Metro is a rapid transit line that runs from Dimotiko Theatro in the west to Doukissis Plakentias or Athens Airport in the east, via Syntagma. Most Line 3 trains start or terminate at Doukissis Plakentias: a through service to the Airport leaves once every 36 minutes, and shares most of the extended route with the Athens Suburban Railway. It runs for 47.3 kilometres (29.4 mi), making it the system's longest line.
Line 3 provides a direct albeit infrequent service between the Port of Piraeus with the Athens International Airport, a journey that takes up to 59 minutes. The line between Dimotiko Theatro and Doukissis Plakentias is underground, and the shared section with the Athens Suburban Railway towards the Airport is a surface-level median of the A6 and A64 motorways.
