Vladimir, a very beautiful city. There are many attractions, such as the Golden Gate Church of the Trinity, and more. This is one ofthe oldest Russian cities. There are beautiful parks and alleys. There are many rivers and beaches. I love a legend associated with the history of the most famous gorodaOdna urban legends connected with the history of conversion of the Golden Gate. In 1767, Vladimir visited Catherine II. But immediately get into the city to the Empress could not - according to one version, her carriage is stuck in the arch of the Golden Gate (despite the 5-meter width of the arch), on the other - Catherine simply afraid to pass under the arch, since that is in disrepair. After this incident, the Empress ordered to repair the monument and demolish part of the fortress rampart, directly adjacent to the walls of the gate to the city could enter freely.
