Tomorrow, the 21st August, is the anniversary of the Apparition at Knock Shrine, and traditionally a busy day at the Shrine.

There's a slight change to the Mass times tomorrow in Knock as a result.

Masses in the Basilica will take place at 12 noon, 5pm and 7.30 - there's no 3 o'clock Mass tomorrow afternoon.

The Basilica will also be open to the public between 9am and 10.30 tomorrow morning, and again from 1-4pm.

The Parish Church will be open for private prayer throughout the day, from 9am to 6pm.
