This Bulgarian national holiday promotes Bulgarian culture and honors two brothers, St. Cyril (c. 827-869) and St. Methodius (c. 815-844), missionaries to Moravia. They are believed to have invented the Slavonic alphabet, also known as the Cyrillic alphabet. Special religious services, concerts, festivals, and student parades are held throughout Bulgaria on this day, which is also known as Saints Cyril and Methodius’s Day, and Day of the Founders of the Slavonic Alphabet. An impressive liturgy, celebrated at the cathedral in Sofia, is one of the highlights. Discuss
