Parliament Square was designed to provide a more open aspect for the new Houses of Parliament built in 1870. It was laid out in 1868 on site of a notorious slum. The square is dotted with statues of famous statesmen, the most notable being Winston Churchill. A statue of Abraham Lincoln sits in front of the Middlesex Guildhall , completed in 1913. Other buildings around the square include Westminster Central Hall, Westminster Abbey and St Margaret’s Westminster. Opposite the Houses of Parliament, across Bridge Street towards Westminster Bridge, stands the rather forbidding Portculis House, completed in 2001. This houses government offices, as well as the ultra-modern, Westminster Underground Station. Today, the square, which became Britain’s first official roundabout in 1926, is normally a traffic jam, although this doesn’t stop its use by the media for interviewing Members of Parliament.
