Belgium Royals Attended The Te Deum Mass On King's Day

King Albert and Queen Paola, Princess Astrid and Prince Lorenz of Belgium attend the Te Deum Mass on King's Day at the Saints Michel Cathedral in Brussels, Belgium on November 15, 2015. Since 1866, for over 148 years King's Day has been celebrated in honour of the Belgian monarch. 15 November marks the first day of the Feast of Saint Leopold in the German liturgical calendar, while it is the Feast of Saint Albert in the Roman Catholic Calendar.

The Te Deum (also known as Ambrosian Hymn or A Song of the Church) is an early Christian hymn of praise. The title is taken from its opening Latin words, Te Deum laudamus, rendered as 'Thee, O God, we praise'.
