A trip here is essential - this elaborate three arcade structure with three tiers is constructed from limestone, marble and granite and was first built in the 1890s. Stalin took over the shopping arcade in 1928 to use as office space, and this was the place where the body of his wife Svetlana was displayed after her suicide, which is where the legend of her ghost wandering the halls comes from. In 1958 it became a shopping arcade again and is today one of Moscow's most popular tourist sights. Toilets for those in need are on the third level of the third arcade and in the basement (enter from the first arcade closest to Red Square).
