The Most Beautiful Churches in London - The Montcalm Hotels
"The mother church of the Catholic Church in England and Wales, Westminster Cathedral is the seat of the Archbishop of Westminster. Opening in 1903, the building is in a neo-Byzantine style, filled with attractive decorative mosaics and constructed from a blend of brick and concrete. The Grand Organ, constructed between 1922-1932, is considered one of the most successful and impressive of its kind."
