Victoria Square (formerly Kyriakou Square) is a large square located in the Municipality of Athens between 3 September and Aristotelous streets. The square's original name was Kyriakou. It was renamed Viktoria in honor of the Queen of the United Kingdom on the occasion of the annexation of the Ionian Islands to Greece in 1864, as a gift to the enthronement of the Queen's nephew, Prince Christian William Ferdinand Adolf George of Denmark, later George I of Greece. Underneath the square passes the Athens Electric Railway at the homonymous stop. The square crosses the streets of Hayden, 3 September and Aristotelous, and in the center of the square is the sculptural complex of Johannes Pfuhl (1846–1914) of Theseus saves Hippodamia.
