Stadiou Street (Greek: Οδός Σταδíου, Odós Stadíou, "Stadium Street") is Athens' major street linking the Omonoia and Syntagma Squares. It runs diagonally and is one-way from northwest to southeast. The street is named after the ancient Panathenaic Stadium located about 3 km southeast of the downtown core and is aligned directly with the ancient stadium.
This street had existed during ancient times. The modern street was originally designed to extend all the way to the stadium. The project was cut short for lack of funding, but the name remained. The street was officially renamed "Churchill Street" after World War II in honor of the British prime minister, but Athenians remained faithful to the traditional name of the street. The same is true of the other two main thoroughfares of downtown Athens, which run parallel to each other and to Stadiou Street: "Eleftherios Venizelos Street" and "Roosevelt Street" were likewise never adopted by the public, which insisted on the traditional University and Akadimias Street, respectively.
Famous buildings on the street are the Bank of Greece building, and the Old Parliament. Klauthmonos Square is a square that is located off the central part of this street; its name literally means "Lamentation Square" (from Κλαυθμών, Klafthmōn, weeping or lamentation) and the Ministry of the Interior is located by it. In the 19th century, Greek public servants were not permanent, but could be hired or sacked on a minister's whim. Following each election, they would gather at this square in order to find out what the election results were: in case of victory of a party other than the one which hired them, they would lament their impending unemployment. Abiding with the aforementioned tradition of downtown Athens, Klafthmonos Square was officially renamed "National Reconciliation Square" but it retains its popular name in almost every context.
