St Basils Cathedral is the iconic building that most people think of when they think of Moscow. It looks fabulous in a picture but even more impressive up close, almost like it should be a Disney castle. The exterior is an amazing riot of colours and textures, which is most impressive in bright sunlight or when it is lit up at night.
It costs 100 rubles to enter the cathedral, which is equivalent to £2, so it is not very expensive. Inside, the walls are covered in frescoes in every room, which are just as colourful as the exterior of the building. Some of the rooms were closed when I was there, but you can still see inside them through the bars.
There are plenty of souvenirs to buy inside, but I suggest you walk around all of the stands before buying anything (look around corners to see if there is another stand). We got ripped off a bit this way, as we bought postcards from the first stand, only to discover that a later stand had them much cheaper. We didn't speak enough Russian to try and take them back.
All in all, St Basils cathedral is a must-see in Moscow. A trip to Moscow would not be complete without viewing this amazing sight.
