Since Iceland's parliament, the Alþingi, was resurrected in 1845, each session of parliament has begun with a Mass at the cathedral, and from there the dean of the cathedral leads the members of parliament to the parliament house.
Siden Islands parlament Altinget (Alþingi) blev genoprettet i 1845, er hver parlamentssamling indledt med en gudstjeneste i domkirken, hvorfra domprovsten fører altingsmedlemmerne til Alþingishúsið.
