means A broad, sweeping view, especially one seen through or framed by an opening or along an avenue.

from From Italian vista, "sight, view," the past participle of vedere, "to see" — itself from Latin videre. The same root sees its way into "video," "vision," and "evident." It entered English in the 17th century alongside a fashion for grand garden design, where a vista was a deliberate line of sight cut through trees to reveal a distant prospect.
