The Diocese of Westminster is one of the smallest dioceses in England and Wales in geographical area, but the largest in terms of Catholic population and priests. The diocesan boundaries include the London Boroughs north of the River Thames, between the River Lea to the East and the Borough of Hillingdon to the West, as well as including the County of Hertfordshire to the North.
Since the restoration of the Catholic Hierarchy in 1850, there have been eleven Archbishops of Westminster. Most recently, Archbishop Vincent Nichols was installed as archbishop on 21st May 2009. In an increasingly cosmopolitan city, the Diocese includes a wide range of ethnic and cultural diversity amongst its Catholic population.
