Alsatia in London, was the name given to an area lying north of the River Thames covered by the Whitefriars monastery, to the south of the west end of Fleet Street and adjacent to the Temple. Between the fifteenth and seventeenth centuries it had the privilege of a sanctuary, except against a writ of the Lord Chief Justice or of the Lords of the Privy Council; and as a result it was the refuge of the perpetrators of every grade of crime, debauchery, and offence against the laws. The execution of a warrant there, if at any time practicable, was attended with great danger, as all united in a maintenance in common of the immunity of the place.
