And now let's get to visiting that famous city and it's hidden interesting places and tourist attractions.

Leadenhall Market in London

Leadenhall Market

Leadenhall Market is one of the oldest markets in London, located in the historic center of London's financial district. Merchants used to sell here fishes and meat from the 14th century but at the end of the 19th century it was rebuilt in Victorian style with the ornately painted roof and cobbled floors. From that time Leadenhall Market became not only a shopping center but also a popular attraction in London.

Do you recognize Diagon Alley from the Harry Potter movie? This was the place where wizards used to buy their spell books, wands, and animals. All scenes from there were filmed in the Leadenhall Market in London.

Nowadays there are a lot of different shops in Leadenhall Market, but it's all organized more like a tourist attraction than a real market. Nevertheless, it's still a great place to visit and feel some Harry Potter magic in London.

Highgate Cemetery in London

Highgate Cemetery

Highgate Cemetery was opened in the middle of the 19th century as one of the city's magnificent park cemeteries to move burials out of the London city. There are a lot of beautiful and mystical Egyptian and Victorian influenced tombs, where gravestones of James Holman, Karl Marx, "Blind Traveler" (19th-century traveler), Adam Worth (famous criminal and inspiration for Professor Moriarty from Sherlock Holmes) and Douglas Adams (sci-fi writer) can be found.

During the World War II cemetery was forgotten and overgrown, which added really creepy feel to the Highgate Cemetery. In the 1970s this place became the Gothic location for the horror movies of the Hammer studio. Because of that films and the vampires in them, Highgate Cemetery in London started to be a more famous place.

Because of all that tales and growing popularity of the Highgate Cemetery, strange things started to happen here. Some tombs were broken open and bodies from them were stabbed by wooden sticks. Those stolen corpses started to lie in strange places.

One neighbor to the Highgate Cemetery even found one morning a body without a head behind the steering wheel of his own car!

All of this happened many years ago and now the Highgate Cemetery is rather a quiet place with just an old, bad reputation, visited by many tourists and locals. Please note: using video cameras and tripods are not permitted and if you want to take photos, only photos for personal-use can be taken here. Highgate Cemetery in London is an awesome place with a great and mysterious atmosphere.

The Mail Rail

The Mail Rail was the common name for the Post Office Railway. It was an automatic underground electric railway built in 1927 to speed Royal Mail package and letters delivery in London.

During its work, over 4 million packages have been transported daily through 8 kilometers long tunnels with the 60 kilometers per hour speed. After almost 80 years, the Mail Rail was closed and abandoned, while many entrances were sealed off.

Interesting fact: During that time many extreme adventurers forced their way into the underground Mail Rail system. Their videos and photos can be still found on the internet.

In 2017, the Mail Rail in London was turned into the Postal Museum that includes the 20-minutes ride on some kind of miniature trains through the Post Office Railway old tunnels.

Sherlock Holmes Museum in London

Sherlock Holmes Museum

Sherlock Holmes house in Conan Doyle's book was located on the Baker Street number 221 in London, just near the Regent's Park. But at the time author of this famous book was writing, this house number did not exist. It's probably because Conan Doyle didn't want to affect any real house.

But this all changed when in 1930 the famous Baker Street expanded and the house number 221B really showed up. This new Sherlock House was given to the Abbey International society, and almost immediately they started receiving many letters asking for the detective's help. Funny thing is that the Abbey International hired a real full-time staff to deal with that cases.

Let's go back now to the actual Sherlock Holmes Museum which was opened in the 1990s on 237 Baker Street, just a few meters from the Abbey International house. The museum succeeds to recreate the quarters of Holmes and Watson from the book, with all the furniture and decorations. The Sherlock Holmes Museum in London is small, but it looks like Sherlock and Watson just left it.

Notice: The Sherlock Holmes Museum in London is small and it's a popular tourist attraction, so there might be queues and a lot of people. Prepare for that.

The Churchill War Rooms

There is a very interesting place in London that it's invisible from the surface. The Churchill War Rooms lies underneath Westminster and during the World War II were the most protected part of England. This is the place which was protecting whole British government as well as Winston Churchill and from here came all the plans how to protect England against the Nazi Germans.

The whole complex of the Churchill War Rooms in London is really well preserved, despite the fact that after the war bunkers were just sealed up and forgotten. In 1984 English government decided to open the tunnels and make here the Imperial War Museum.
