I always think Westminster Cathedral is overlooked in favour of its more glamorous neighbour, the Abbey, just down the road. Built on the site of Tothill Fields Prison, the Cathedral first opened its doors to celebrate daily Mass in 1903. It was thanks to Cardinal Manning, who purchased the site in 1884 that the Cathedral is here at all. Round the back is the famous Cathedral Choir School, an academically selective Roman Catholic Boys Prep School for about 200 boys aged 4 - 13.
