“Holy Savior Cathedral (Armenian: Սուրբ Ամենափրկիչ Վանք, Surp Amenaprgich Vank; Persian: کلیسای وانک or آمنا پرکیج, Kelisa-ye Vank or Amenapergich; ), also known as Vank Cathedral and The Church of the Saintly Sisters, is a cathedral in Isfahan, Iran. Vank means “monastery” or “convent” in the Armenian language.
Construction is believed to have begun in 1606 by the first arrivals, and completed with major alterations to design between 1655 and 1664 under the supervision of Archbishop David. The cathedral consists of a domed sanctuary, much like a Persian mosque, but with the significant addition of a semi-octagonal apse and raised chancel usually seen in western churches. The cathedral’s exteriors are in relatively modern brickwork and are exceptionally plain compared to its elaborately decorated interior.”
