The 4th Plinth of Trafalgar Square

What is the Fourth Plinth?
The Fourth Plinth is in the north-west of Trafalgar Square, in central London. Built in 1841, it was originally intended for an equestrian statue but was empty for many years. It is now the location for specially commissioned artworks.

In my opinion ,it's a very useful thing but to my mind it's a pity that it was empty for many years.
If I was at their place, I would put a very precious statues, which is very quiet, like me,and horses, which is my favourite animal. I would like to put this things to decorate the town for tourists and to show to people who I am really.
