Jolfa is the Armenian quarter of Esfahan. It was bit away from the center but they had coffee shops with real Espresso machines and the like, so off I went. There were a few churches which were worth a visit. The Vank Cathedral supposedly has the nicest frescoes. However, I liked the Church of Bethlehem the best. Every square inch of the interior was covered with frescoes.
For the rest there was not much of interest in Jolfa. I was half expecting a situation similar to Aleppo in Syria, where the architecture in the Armenian quarter was quite distinct from the rest of the city. No such luck here.
