“Since its construction in the early 1800s, Trafalgar Square has been seen as a centre of national democracy and protest. Rallies and demonstrations are frequently held at weekends on a range of political, religious and general issues. The Mayor supports this democratic tradition, and gives access to the square for such causes” (London.gov.uk).
