You can’t miss Trafalgar Square – in the very heart of London’s west end. But it’s a relatively new addition to the city and the area was once very different – quite seedy in fact.

So here are a few things you may not know about Trafalgar Square:

Royal stables – the northern part of what is now Trafalgar Square were actually the royal stables, dating back to King Edward I. Basically, take as your starting point the National Gallery, tear it down in your mind and put up stables with horses and falcons instead.

This kind of makes sense because the “Royal Mews” would  have been in close proximity to the sprawling medieval palace of Whitehall nearby. The crown owned the land and so converting it to a public square was pretty straight forward.

A workhouse off Trafalgar Square – it may seem incredible now but on the site of the National Portrait Gallery, just off the square, there was a large workhouse for the poor from the 17th century until 1871 when it was demolished to allow for an extension to the National Gallery.

If you look at the map, you can see that the workhouse was just behind the gallery. It gained a dreadful reputation for overcrowding and insanitary conditions. Ventilation was very poor and there was an absence of toilets. A guide to London I have from 1804 states that people could pay to go and gawp at the inmates – rather tasteless!

Gordon of Khartoum – now absent from Trafalgar Square – General Gordon was a hero to the Victorian public. He had earned a reputation for military valour fighting for the British Empire in China. And he was then sent to Sudan where a messianic figure nicknamed the “Mad Mahdi” was leading an uprising against colonial rule.

Gordon overreached himself in trying to put dow the rebellion and was killed by rebels in the city of Khartoum. A statue of him was put up in Trafalgar Square in the 1880s but quietly removed to the Embankment in 1953.

St Martin’s in the Fields – predates Trafalgar Square – an early 18th century church built by the architect James Gibbs. It pre-dates Trafalgar Square by over a hundred years. So when the Victorians started clearing away old buildings to create this huge public space, they considered removing the steps up to the church to make more room for traffic. It was even suggested that the pillared portico at the front of the church should be taken down and re-erected round the back!

“Bloody Sunday” – When you say Bloody Sunday now, people are more likely to think of events in Northern Ireland in the 1970s. But the original Bloody Sunday was a workers demonstration on 13 November, 1877 in Trafalgar Square that ended up as a running battle between the police and trade unionists, socialists and Fenians.

I was in Trafalgar Square as a journalist in 1990 when the poll tax demonstration descended into violent rioting – a scene I shall never forget.
