“In the Catholic Church, a Eucharistic congress is a gathering of clergy, religious, and laity to bear witness to the real presence of Jesus in the Eucharist, which is an important Catholic doctrine. Congresses bring together people from a wide area, and typically involve large open-air Masses, Eucharistic adoration (Blessed Sacrament), and other devotional ceremonies held over several days. Congresses may both refer to National (varies by country) and International Eucharistic Congresses.”
