GUM is a mall in Moscow's Red Square. Besides being a huge building, one of its attractions is that the stores inside are luxury stores.
This building used to be the State's General Store during the Soviet regime, but it has now become one of the most important and spectacular shopping centers in the city. The building's interior structure is stunning and imposing, full of glass domes and wide halls filled with luxury exclusive stores only affordable by the wealthiest pockets. The best time to visit the shopping center is in Christmas: the outer and inner decoration is worthy of a fairy tale.
