If you have time for only one walk in London, then this is the one. It will take you past the seat of government; not only the Houses of Parliament, but the classical buildings of the old War Office and Admiralty, and the current Foreign Office and Treasury. Plus the sites of four palaces: Whitehall and Westminster, long gone, and Buckingham and St James, both very much there. The political parties for many years had their bases in Smith Square, and the area is still home to many MPs.
Throw in a cathedral, and one of Londonís finest parks, and finish up in Trafalgar Square which is the centre of London as measured by the map drawers and signpost makers.
Watch out for blue plaques commemorating memorable people (and some youíve never heard of), and donít be afraid to divert onto a bridge for the view, or poke your nose in a side street to see whatís there, before returning to the walk.
You will see much more than I shall describe, but here are a few of the sights.
Early on you'll pass Whitehall Court and the Old War office, their architecture uncelebrated because they were built in the late nineteenth century in out of date styles; yet both are impressive and beautiful and their rooflines compliment each other.
This picture is looking towards the Horse Guards, with the Old War Office visible on the right, and the end of the Banqueting Hall on the left.
The Banqueting Hall is the only remaining part of Whitehall Palace. One of the very first classical styled buildings in England, it was also where Charles I stepped out of an upper window onto a specially erected scaffold to be executed.
This is the Old War Office again, looking back from the Horse Guards.
No doubt you'll notice the horses and the guards at the Horse Guards, but also admire the symmetrical design of their building.
From the gravel yard at the back youíll see the red brick rear portion of the Admiralty, from where Britainís great navy was commanded in the years of Empire. Itís just possible you wonít be allowed on that gravel if the Trooping of the Colour ceremony is taking place, as it does on a Saturday each June.
The Houses of Parliament are pictured at the top of the page, not from the walk but from the other side of the river.
Pedants may tell you Big Ben is the name only of the largest bell, but Londoners have been using it as the nickname for the distinctive tower for probably 150 years.
These simple, elegant Georgian terraces in Lord North Street were put up early in the eighteenth century, and have been used as homes and sometimes offices by Members of Parliament through the years.
Soon you will enter Dean's Yard, a quiet sanctuary surrounded by Church buildings and those of Westminster School. When you leave you'll see the main entrance to Westminster Abbey. It's not pictured here, but you'll spot it.
The same applies to the Methodist Central Hall and the stunning houses in Queen Anne's Gate, adorned with a surprising number of blue plaques.
Here is the view from the bridge in St James's Park, looking across the lake which is populated by many varieties of waterfowl, including pelicans. The fairytale castle effect is created by the roofs of Whitehall Court towering above those of the Old War Office and the Horse Guards.
On a summer Sunday, you might have to wait to occupy the best spot by the railings, but it's worth it. Londoners who live in Pimlico, as I once did, might use this as part of their route to work in the West End, and enjoy the view just as much on a damp Tuesday in November.
The walk has taken you through the sites of Whitehall Palace (burned down 1698) and Westminster Palace (burned down in 1512, though the name is still used for the Houses of Parliament). Now we turn and look the other way to see Buckingham Palace, principal residence of the Queen.
You will go close to the Palace, to peer through the railings and admire that golden memorial to Queen Victoria which you can see in the picture.
From there you'll walk through another park to pass another palace, St James's, main residence of eighteenth century kings, derided by some foreign diplomats and courtiers as a dull place lacking luxury.
The remainder of the walk takes you along Pall Mall, where clubs for distinguished gentlemen line the road. You may be able to glimpse chandeliers and hints of luxury. If you're nosey, the top deck of a number nine bus will enable you to peer inside.
The most spectacular of these is the Atheneum, on the corner of Pall Mall and Waterloo Place, distinguished by its blue frieze. Near here there are fine terraces designed by John Nash, architect to the Prince Regent and originator of the Regency style.
Finally you will see Trafalgar Square, with Nelson's Column, King Charles I's statue (which marks the centre of London), its view down Whitehall to Big Ben, and the fountains which people throw themselves in on New Year's Eve.
On the northern side of the square is the National Gallery, with the largest and finest collection of art in Britain. Near the gallery is St Martin's in the Fields, arguably the prettiest classical church in London (see left).
