Restoration of the chapel of Auvergne was completed in May 2013 under the initiative of The St John’s Co-Cathedral Foundation. The project consisted of the restoration of the gilded wall carvings, the reredos and the two lunette paintings depicting ‘The Martyrdom of St Sebastian’ and ‘St Sebastian Meeting Pope Pius Caius On His Way To Martyrdom’, both by Giuseppe D’Arena, and the titular painting of The Martyrdom of St Sebastian attributed to Lucas Garnier. The paintings were cleaned, relined and pictorial integration was carried out where necessary and a layer of protective varnish applied as a protective layer.
