On May 25,2013, about 2000 people attended the liturgy the Ecumenical Patriarch Bartholomew celebrated in Mikulcice, a place linked to the medieval Christian missionaries Sts Cyril and Methodius, in spite of the rainy weather.

The liturgy was held to mark the 1150th anniversary of the arrival of Sts Cyril and Methodius in Great Moravia from Thessaloniki, then the Byzantine Empire.

Pilgrimages to Mikulcice take place annually in honour of the two saint brothers who created a special script for Slavs and translated basic Christian texts into the Slavic language.
