Beyza
Beyza (, also Romanized as Beyzā, Beyẕā, and Bayzâ; also known as Tall-e Beyẕā, Tal-e Baiza, Tol-e Beyẕā, and Sepīdān) is a city in and the capital of Beyza District, in Sepidan County, Fars Province, Iran. At the 2006 census, its population was 3,593, in 845 families.
Beyza's ancient name was Nesayak or Nesa. Linguists derive this name from the Parthian word Ns'yk meaning "bright, shining". Arabs during their invasion of Iran translated this name in Arabic Bayda which also means "bright and white". The ancient Elamite city of Anshan is sometimes believed to have been situated there. Legend attributes its foundation to Gushtasb.
