Embankment
At first, when the London Underground was built, trains were hauled by steam locomotives. But the smoke from the locomotive chimneys would soon have suffocated the passengers. That's why vents were made in the tunnels to let the sneaker out. Later, when electricity started to move the trains, these openings were no longer needed for the new lines, and the tunnels were also built deeper. But the air vents of the old tunnels are still there. But you hardly ever notice these while walking in London. Many such vents are located in courtyards between buildings. But when they are in public, they are very well disguised. You can see such places in the following two photos. In the first case, the hole is surrounded by a dense hedge, in the second, it is located behind the statue. When exiting the underground station by the park, you have to walk in the northeast direction.
Embankment
A very peculiar street. It would be like some kind of basement tunnel, but actually in street rights. All the houses around it have been built new, the street is the only thing that remains from the time when completely different houses stood here. Recommended for a walk in the evening, then it must have been haunted here. 
Sloane Square
Sloane Square - The 'Venus Fountain'. It has been standing here on the square since 1953. Sculptor Gilbert Ledward. The upper part shows Venus, while the lower vase-shaped part has scenes of King Charles II with his mistress Nell Gwynn by the Thames. Unfortunately, these images cannot be seen well in flowing water, much less can be photographed.
Tower Hill
All Hallows by the Tower is a very old church. There are many interesting things to see there. But it's also worth going down to the basement. In one place, the floor is the stone pavement of the road built by the ancient Romans, which later remained in the basement of the building under construction. But in one of the showcases you can see a church book in which the marriage of John Quincy Adams, the 6th president of the United States, to Louise Catherina Johnson on July 26, 1797 in this church is recorded (the paper with an arrow indicates this place).
Borough
Church of St. George The Martyr. The four clocks of the tower face different directions. At night, three dials are illuminated, the fourth is not. Why, I don't know exactly, but people know how to say that the people there did not want to pay the church tax.
Paddington
A very quaint pedestrian drawbridge quite close to Paddington station. There is also another bridge on the same canal, which turns into a roll. They are usually raised on Fridays at noon.
Charing Crosss
A building with a gate leading to a square called Horse Guard Parade. But there is a clock at the top of the building. Well, so what? But if you take a closer look at the clock, you will notice that there is a dark spot on the face of the otherwise nice clock at two o'clock. Why? If we mentally step twenty meters to the left of the place where the second picture was taken, we are at the place where King Charles I was executed. And it happened exactly at two o'clock in the afternoon. Some doubt it, but no one has offered a better explanation.
Marble Arch
Former Russian spy Alexander Litvinenko was poisoned with polonium isotope 210 in the Millennium Hotel restaurant. The amount of the substance added to the teacup costs over a million dollars on the open market. Undoubtedly the most expensive cup of tea ever. The owners of the hotel must have been scared, now this hotel is called The Biltmore.
Charing Cross
Currently, all public transport in London is united under the name TfL (Transport for London). It is very convenient, with your transport card you can use all trains, buses, trams. Of course, this has not always been the case, at one time there were a large number of companies that kept appearing, disappearing, merging and, of course, competing.
But the colorful history of London transport is gathered in the relevant museum right on the edge of Covent Garden market. A place that is really worth visiting, interesting for both adults and children. There are also interactive exhibits that children can touch with their hands.
One man seems to hold a mobile phone.
Cannon Street
A stone that is considered a symbol of something important. What exactly, is not very clear.
Igal pool Elizabeth Line is a recently completed rail transport line. It does not count as an Underground, nor does it count as a railway. Something special. Enormous long trains, moving quickly and quietly, connect the various fringes of London through the city center. Completion took longer than expected; it cost more than prognosed - but it is really magnificent!
Piccadilly Circus
Equestrian Monument to William III. There seems to be a boring equestrian figure. Who cares about this king who ruled from 1688 to 1702 and his riding? But in fact, the monument hides a secret sign in itself. William III died falling from a horse when his horse stumbled upon a pile of mole soil. And if you look carefully at the monument, we can also see this pile of soil under the horse's foot.
Queen's Park
The Carlton Tavern, an old pub. But it's actually "Version 2". A real estate developer wanted to build a house here, like the one on the right in the picture. But he wasn't allowed to do that because the building was a national monument. Under some pretext, the developer managed to close the pub for a few days and in one night the building was demolished. But the developer obviously regretted that. The case went to court and the developer was ordered to restore the building exactly as it was at his own expense. The laws are tough there. The developer had to do it. It was made easier by the fact that there were very accurate drawings of the listed building.
Paddington
A nice group to the left of Paddington station. Two of the taburets are still empty, you can sit in the company.
St John's Wood
Bridge over the Regent Canal. In the second photo you can see the grooves in the pillar. These were worn away with ropes when the ferry was hauled from the shore by horses. But the grooves are on both sides of the pillar. Why? It has to do with the fact that this bridge has been built twice. Once, a steam-powered boat was towing a barge with over a tonne of gunpowder as cargo. But it was apparently under this bridge that a spark flew from the chimney.... The explosion destroyed the bridge. Some parts of the boat are said to have been blown several hundred metres away. But the massive pillars survived intact and were put back in place when the new bridge was built. And some of them apparently the other way round, which explains the grooves on either side.
Marlebone
There are around 1,000 blue round signs in London, marking places where famous people have either lived, worked or stayed. But this one is special. Danger Mouse was a secret agent from the cartoons of the eighties, a great favourite with British children.
Royal Arsenal
The royal arsenal. This is where cannons were cast for the British army. The first picture is not of a church (as might be mistakenly thought), but of a foundry.
Leytonstone
"The King of Horror" Alfred Hitchcock was born in Leytonstone, East London. His birthplace is no more, the site is now a petrol station. But in front of Leytonstone tube station, in the connecting corridor, there are mosaics of his films on the walls. It's good to quiz yourself on how many films you recognise.
Pinner
St John the Baptist church garden. A curious grave monument. Legend has it that a man ordered a person to be paid a monthly allowance from his property 'while he was still on earth'. After his death, it was decided that the coffin should be raised high above the ground so that the person would continue to receive the allowance.
An interesting legend, but not true. In fact, the man and his wife are still buried underground. Their son designed this strange grave monument. I don't know why.
Angel
Once upon a time, there was great enthusiasm in England for the discoveries made in Egypt. Sphinxes became very popular as a result. One interesting example is Richmond Avenue, where all the houses on one stretch are decorated with tiny sphinxes.
Temple
We've probably all seen lots of pictures and statues of angels. But have you ever seen an angel talking on the phone?
Earl's Court
Such signs can be seen all over London. And you can believe that nothing really happened at the time shown here. In fact, with the change from the Julian to the Gregorian calendar, the day simply disappeared. Nothing can really happen on a day that hasn't happened
Liverpool Street
All that remains of the old house is the front wall, with a new house built behind. There has been some respect for the old house though, the old doorway has been blocked up and is probably a different colour quite deliberately.
Putney Bridge
During the Second World War, it was feared that German troops might invade London. Therefore, special defences were built in key locations, such as railway stations, from which invaders could be fired upon if necessary. Most of these did not survive, but one can still be seen at Putney Bridge station.
Putney Bridge
At one time, there were many special kilns for firing ceramics in London. Few survive, for example one in North Kensington. But this one is really just an advertisement for a ceramics company.
For us, perhaps, the word "pottery" is associated with flower vases and other trinkets. But what about the stones from which many of London's beautiful houses are built? And even the lion you see at the eastern end of Westminster Bridge has been 'matured' in sections over four days in a steady fire in a ceramic kiln.
Pimlico
During World War II, it wasn't just central London that was bombed. Houses in the suburbs were also hit. Here too, a house once stood. But all that remains of it is the fireplace used to heat the rooms.
Liverpool Street
Don't think this sauna is tiny. As is the custom here, important rooms are underground.
Aldgate
The drinking water pump is first shown on a map in 1574. But the townspeople were getting their water from here much earlier.
King's Cross
This "beacon" was probably built just to decorate the house. There is no navigable waterway nearby where it can be seen. The only real lighthouse in London is at Trinity Buoy Wharf. But even that is not intended for navigation, but as an educational tool for sailors.
Manor House
Abney Park Cemetery. Interesting in that the trees are planted in alphabetical order from the entrance to their Latin names. A number of famous people are buried there, including of William Booth, the founder of the Salvation Army. There's also a memorial to those who took part in the Air Wars and a nice chapel, which until recently was in a poor state of repair. But now looks excellent.
