Kastellorizo or Castellorizo (Greek: Καστελλόριζο - Kastellorizo, officially Μεγίστη - Megísti or Meyísti) is a Greek island and municipality located in the southeastern Mediterranean. It lies roughly 2 kilometres (1 mile) off the south coast of Turkey, about 570 km (354 mi) southeast of Athens and 125 km (78 mi) east of Rhodes, almost halfway between Rhodes and Antalya and 280 km (170 mi) to Cyprus. Kastellorizo is part of the Rhodes regional unit.
The island's official name, Megisti (Μεγίστη) means "biggest" or "greatest", but at only 11.987 km2 (5 sq mi) in area, it is the smallest of the Dodecanese. The name, however, refers to the fact that it is the largest of the small archipelago. This name was used in antiquity, but is now rarely used in Greek, the name Kastellórizo (Καστελλόριζο) being common since the twelfth century. There are several hypotheses about the origin of this name. "Kastello" derives from the Italian word "castello", meaning "castle". There is some argument on the second part of the name. The arguments are centered on the following possible origins of the element rizo:
Once in a dream
Far beyond these castle walls
Down by the bay where the
Moonlit water falls
I stood alone while the minstrel sang his song
So afraid I'd lost my soul
There in the fog his song kept calling me
Leading me on with its haunting melody
Deep in my heart a voice kept echoing
I knew I'd soon be wandering
Far beyond these castle walls
Where the distant harbour meets the sky
There the battle rages like hell
And every dove had lost its will to fly
Far beyond these castle walls
Where I thought I heard Tiresias say
Life is never what it seems
And every man must meet his destiny
