By some accounts, Lviv has more than 100 churches and it's all too easy to overdose on ornate interiors and golden iconostases, but one church you should not miss is the elegant 1363 Armenian Cathedral. The placid cathedral courtyard is a maze of arched passageways and squat buildings festooned with intricate Caucasian detail. Stepping into the courtyard feels like entering another era. Outside, quaint, cobbled vul Virmenska was once the heart of the old Armenian ('Virmenska' in Ukrainian) quarter.
