The arch was an impressive structure. It had four brick tiers; the towers’ height was 19 m, width - 7.1 m and length - 16.3 m. The functional purpose of the arch was to inspect and register all arriving travelers. Throughout
the entire duration of its existence, the Moscow Arch was inseparably linked with the history of Irkutsk. Through this arch came virtually all travelers, writers, researchers, public figures, diplomats, who visited
Irkutsk since 1813 till the end of XIX century. The arch was dismantled in 1925 because of its disrepair and recreated in 2011, when the city celebrated its 350th anniversary.
By the Arch there is a landing pier where you can take a 30-minute cruise on a boat on the river Angara.
