A central and prime location in the city, Trafalgar Square is located in the city of Westminster and is a public square with many cultural spaces, museums and galleries around the square. Distances to other places are measured from Trafalgar Square, which was initially designed by famous architect John Nash in the 1820s.
A location as central as Trafalgar Square gives you access to many other fun tourist attractions to be at, like ChinaTown, Big Ben, and even Buckingham Palace. It is named after Admiral Lord Nelson who led the British to victory in the Battle of Trafalgar in 1805.
Erstwhile known as Charing and Charing Cross, present day Trafalgar Square was asked to be redone and redeveloped by King George IV. However, before he could see his plans come to fruition, Nash passed away. A new design was proposed by architect Charles Barry, with its construction taking 5 years and getting completed in 1845.
