Every city has its own unique feel and vibe, which is determined by a number of things. The local historic sites are no doubt one of the largest contributing factors to the aura that surrounds a city. When in London, users recommend paying a visit to Tower Bridge Exhibition, in the City area to get a feel for what truly makes up the city. Once you have been there, you can take a walk on through the city, along the river Thames which has provided the life blood to this city for centuries, being the conduit to the outside world, and the bringer of new things in. Buildings tower above you and architecture through the ages abounds everywhere you look. From the oldest democracy, to the spoils of a great empire, the museums, buildings, parks, streets, houses, canals and rivers all have a story to tell. And the story is really the people who make up, and made up London through the ages, who brought in their influences, and continue to do so, who make the city the great melting pot that it has always been and still is today. There are so many historic places in London it is difficult to narrow it down, but take a tour of some of the best, and they will provide you with a little snapshot of a great world metropolis.
