The Catholic church of Our Lady in Lillington (now a suburb of Leamington Spa) was opened in 1963 and is quite simply one of the most stunning modern churches I've ever seen.
The building, designed by Henry Fedeski, follows the traditional cruciform plan but with a centrally placed altar at the crossing. However the most outstanding element here is the sheer abundance of (mostly) abstract stained glass, bathing the interior in a magical kaleidoscopic light.
The glass is the work of Dom Charles Norris, who led a team of monks at Buckfast Abbey in employing the dalle de verre (slab of glass) technique, wherein thick chunks of coloured glass are set in a concrete matrix. Norris's best known work is at Buckfast Abbey and at Harlow (a church remarkably similar in many ways to this one).
The entire clerestory of all four arms of the building consists of this rich abstract glazing. A round window enlivens the entrance facade (liturgically west but the church is actually orientated north to south) whilst the transepts are dominated by huge images of Mary and the Archangel Gabriel respectively (the only figurative elements in the glazing). There are yet further examples of this rich glass in three of the side chapels and annexes at ground level, all in all making a visit to this church an unforgettable experience.
This is a magnificent building which clearly deserves to be better known, there can be few such significant examples of dalle de verre glass in the country.
Alas the church is normally locked outside of services so it is best to make special arrangements or attend mass to see inside.
