The new Chapel at St Deiniol's is a quiet space where people can pray and reflect either on their own or in a group. There are daily services and everybody is welcome to attend with seating available for forty people. Groups of all denominations are welcome to use the Chapel as a retreat venue on a residential or daily basis.

The Chapel provides a discreet spirituality from day to day like the "quiet breathing of the house". The ethos of the Library and Chapel is deliberately inclusive and people are accepted as they are, irrespective of their gender, sexual orientation, ethnicity or religious background.

The rest of the Library's facilities are available to any group or individual using the Chapel who wish to enhance their stay. Hawarden is a friendly, historic village and visitors can enjoy scenic walks in nearby Hawarden Park, part of the Gladstone Estate.
