Alimos (Greek: Άλιμος), Latin and older form: Alimus, is a suburb in the south southwestern part of Athens, Greece, also known as Kalamaki (Καλαμάκι, older forms: Kalamakio and Kalamakion). Poseidonos Avenue runs in the western part of Alimos, with the Hymettus mountain to the east meeting mainly grassland, while areas to the north of Argyroupoli are forested. The nearest subway station is at Alexandros Panagoulis station and is also accessed by a tramway constructed in the 2000s, and opened in 2004, serving as access with the Attiki Odos (number 63) to the east. Vouliagmenis is to the west, and the area lies South of Athens, Southeast of Piraeus, Northwest of Sounio, and almost directly north of the old Ellinikon International Airport, which served two entry points and several Olympic venues, including a basketball arena. The Saronic Gulf is located to its west.
