This was not what expected. The words Kremlin and growing up in the Cold War meant something foreboding. Visiting the Kremlin was bizarre. It really is quite small, is a fortress and has three small churches which are named as cathedrals. I would not have been able to have visited Moscow and not visited the Kremlin but it was not the highlight of my visit to Russia. The cathedrals are small and are difficult to enter because of the many and annoying tour groups, but it is a must see visit. We bought online tickets in advance and collected the tickets early in the morning. The normal ticket entrances were long. You do need to decide what day you wish to visit. We chose not to visit the armoury and don't feel as if we missed out. We spent around 2 hours here and this was plenty of time to emjoy the Kremlin.

The tour of the Kremlin was just superb packed with history and it is very much necessary that you have a guide for the trip. The word Kremlin in Russian means a fortified citadel or fortress in the city. Built between 1435 and 1495 has 20 towers connected by a wall in an irregular triangular shaped fortress which overlooks the Red Square.
The Kremlin sits on Borovitsky Hill, rising above the Moscow River in the centre of the city. It was the religious centre of the Russian Orthodox Church and also the residence of the Tsars.
Inside the Kremlin walls are the grand cathedrals and palaces from different periods, museums, the Armoury and the Russian Diamond Fund. During the Soviet era, the Kremlin became an exclusive quarter where the state’s governing elite lived and worked. It was also the official residence of the President of the Russia.
Despite all the tragic events in history, the Kremlin is a majestic piece of architecture and a must see in Moscow

We not only took tours inside but you don't really get a sense of the walls until you drive around it and really see it from a distance. If you are on a tour, they will do that. It stands out against all the white and gold domes around.
