A group headed by Bishop Victoria Matthews and including architects from Warren and Mahoney is to embark on a world tour for inspiration for a new Cathedral in the Square.
The bishop and her companions will visit Britain, Europe and the United States to view 12 cathedrals and relevant buildings.
The buildings to be studied include Coventry Cathedral, which has retained the ruins after bombing during World War II, as well as St Martin-in-the-Fields in London.
In Europe, the bishop will view La Sagrada Familia in Barcelona, a cathedral that is still being finished.
