In the 18th century, the postal gates of Penza were located on its outskirts, near the future Karakozov Street. From here began a long and dangerous journey to Moscow. In 1981, an unusual monument was erected at this site, featuring a pyramidal stone obelisk, a watchman's booth, and a barrier, in memory of the postal station. Once, there was a real postal station with an inn and a stable, where all the city correspondence was brought to be then distributed by couriers across the country. According to the rules, such stations were supposed to be located every 40-50 versts, but sometimes the drivers could travel much further without encountering anyone. These stations also served as resting places: travelers could rest, and coachmen could change horses. State correspondence was transported in special carriages drawn by a troika. Urgent messages were delivered without stops: at each station, the courier would transfer to a new diligence and continue the journey. In such cases, the drivers worked in pairs, taking turns. In the 19th century, it was planned that the street Moscow would end here, originally arising as a road to Moscow. However, in 1874, the construction of the Penza-I station and the railway separated this part of the city from the center, and the architectural plans were never realized.
