This monumental granite structure serves as a tribute to V. I. Lenin, and the final resting place of his embalmed body. There are plenty of people waiting to see it, so you can only stay there for a few minutes, but it's one of the things everyone visiting Moscow should see. You are not allowed to take backpacks or bags into the premises, and you can't take pictures.
Open on Tue, Wed, Thu, Sat, Sun: 10 a.m. - 1 p.m.
Admission to the mausoleum is free.
