The Church of One day (Church of the keys). I came to get the key. You can get to M. Vesnegiler, or from Sultanahmet's side on T1. The church is not primitive, it stands behind the set, the landmark is on the cross on the roof. Entrance to the courtyard, at the entrance to the church there is a "place" for candles. They don't put it in the church. Inside you can buy candles and keys (landmark 2 candles and 2 keys up to 150 lira). Bypasses all the icons, mentally open the key, before making a wish, or ask for what is in your heart. After that, you can approach the priest, tell the country and your name (do not be afraid even if you do not know the languages), the priest will read the prayer, bless. Leave a donation in the box. And then you can put candles on the street.
