Let us start from Queen Anne’s Gate in the heart of Westminster. Go through one of two entrances onto Birdcage Walk, cross the road into St Jame’s Park, and then take a route diagonally through the park. Keep the lake on your left, and skirt round the tourists of every tribe and nation – it is nearly always very busy here. As you come round the head of the lake, cross over the road and take a diagonal path across the miniature gravel plain that is Horse Guards Parade.  Whenever I cross here, I am reminded of an old picture of Winston Churchill as a young politician crossing Horse Guards in company with Sir Edward Grey, on the eve of the Great War. The building on the left as you cross, the one with the aerials and wires on top, is the Old Admiralty Building. It resembles – as well it might – Britannia Royal Naval College at Dartmouth.

Go through the arches onto Whitehall, turning left towards Trafalgar Square. This the place where the two mounted sentries are often photographed by tourists. As you come onto Whitehall, you can see Nelson’s Column in the distance. Going up Whitehall away from Westminster, on the right there is a pub called “The Clarence” which I highly recommend. My wife and a friend of hers went in here some years back, on a trip to see the Queen, and they had no food left except for some Scotch Eggs, but this they served most graciously and cheerfully. She was impressed with the service. I’ve quite literally gone out of my way to eat there ever since – eaten there with my wife at least twice, with colleagues from work, and on my own. They have some great upstairs rooms which aren’t always as busy as the main room downstairs. 

Cross Trafalgar Square – generally best done by going to the right, from Whitehall, crossing the entrance to the Strand. Science-fiction author Stephen Baxter wrote a novel about the flooding of London, and his tip, if central London is flooding, is get above the Strand. The clue, as he notes in his book “Flood”, is in the name…

Keeping St Martins-in-the-Fields on your right, the National Gallery will be on your left. At this point, Charing Cross Road dog-legs to the left; if you wish you can follow it to Cambridge Circus, and then turn right along Shaftesbury Street. But the more direct route is to turn slightly to the right and then straight on, along St Martins Lane though Covent Garden. It’s a very relaxing walk along a reasonably quiet road traffic-wise, passing different pubs and restaurants. What you will see, is two unusual and complex road junctions. Inner city five-road junctions are fairly common in the UK. But six-way junctions in the inner city – three crossing roads – not so much. And seven roads, as at “Seven Dials” – very much rarer still. One comes out on Shaftesbury Avenue just near the Forbidden Planet store. Along here is a little café called “Franx” which I like to stop at sometimes.

Continue along a pedestrianised section of Shaftesbury Avenue a hundred yards or so and you find yourself on New Oxford Street – the A40 in fact. Take a right along here, and then a slight left onto Bloomsbury Way, with the main flow of traffic, leaving New Oxford Street behind. At this point the streets are broadly NW/SE and NE/SW. The British Museum is about two blocks away on the left. Continuing along Bloomsbury Way, you will see on the right the Swedenborg Institute”, a modest building devoted to the writings of the philosopher Emmanuel Swedenborg. Further along, on the left, a park – Bloomsbury Gardens. On the right, at the junction with Southampton Row, you’ll see Sicilian Avenue, a delightful pedestrianised interlude of Italianate cafes and shops, under repair in these times, but well worth a visit if you’re in the area.

One thing you will notice on a long walk across London, is the changing architectural styles and the changing atmosphere. Once in Southampton Row, you’re no longer in West London. Really, even though we’ve still to cross the Euston Road, we’re in North London. Here there are shops and restaurants, little dentists and minor medical institutes, and as we approach the station district, a number of slab-sided hotels of differing age and architectural merit. Passing Russell Square on your left (and the tube station on a minor side-street on the right), Southampton Row becomes Woburn Place and then, Tavistock Square. In this quarter, we start to see various hospitals and big, important institutes. You will pass, for example, the headquarters of the British Medical Association. The road continues, and intersects with Euston Road adjacent to the St Pancras New Church, a Regency-style church which I still have not visited. At this point, the depressing 1960’s heap that is Euston station, is on your left across the very busy Euston Road. It’s not widely understood that Euston, St Pancras and Kings Cross are all within half a mile of each other.

But we will take a step backward here. If you turn right off Southampton Row near Russell Square, you can find Coram Fields, a rather lovely inner-city park. This is a university quarter too – the streets are full of students from all over the world. Some of them go for lunch, at a branch of King of Falafel on Tavistock Place, where it crosses Hunter Street and Judd Street. I found this quite by chance one day when wandering through this great city. Here is another great place to just sit at a café at a road junction and watch the world go by, some on foot, some, on their bikes. I was sat here once when the bin men arrived, and I watched the proprietor put together a bag of samosas for the bin men, and give it to them with a smile. Heart-warming: another place I will literally go out of my way to visit.

Let’s go back to Euston Road. Euston Road is part of a great E-W arteries across the centre of London, stretching from Shoreditch in the east, curving north-west to the Angel, Islington (which we will cover later in another London Walk), west to Kings Cross, then south-west to Regents Park, Marylebone and Paddington before it becomes the Westway. It is always a busy road, an artery pulsing with the blood of the city, the hustle and bustle of people hurrying from one place to another. Crossing the road with care, you can then see the British Library – that building that King Charles once called a “monstrous carbuncle”. Personally I don’t agree. The Barbican, or perhaps Euston station – now they are “monstrous carbuncles”.

Next door is the still-magnificent St Pancras Hotel, now beautifully restored and consequently too expensive for most of us to stay at. Outside, on the station forecourt, you will see a purple sports car easily worth hundreds of thousands of pounds. I wonder that the hotel keep it here purely as a tourist attraction. I’ve no idea what sort it is. People take photographs of it, but I take Shania Twain’s view – “OK – so you’ve got a car.”

Carry on up the slope to the far entrance to the station. Going in this entrance rather than coming into the undercroft where all the shops are, you can catch the full glory of St Pancras, to my mind one of the most dramatic and startling railway stations in Europe. When it was built, it was the biggest single arch iron-spanned roof in the world. It is still eye-catching, painted today in a pleasant sky blue. As someone who remembers St Pancras in the dark days of the 1990’s, the Eurostar terminal it is a vast improvement on what it was. In front of you, there will be three or four Eurostar trains. On the right, the Betjeman Arms: maybe time for a refreshing pint after our walk.
