You Are Missing Out Big Time If These Churches Are Not In Your London Itinerary
"There are many beautiful churches in London and Westminster Cathedral is certainly one of them. Located in proximity to Victoria Station, this is the mother church of Roman Catholics in England and Wales. The exterior is made of red and white brick, showcasing the neo-Byzantine style architecture while the interior, made with 120 different types of marbles, is equally fascinating."
