Royal Route to obok Skarpy Warszawskiej najbardziej charakterystyczny element w krajobrazie Warszawy, which gives the city an individual, face partially valid to this day. Its history goes back to the times of the Saxons (years 1720-1764), when two more kings from the Wettin dynasty, August II i August III, made an attempt to transform Warsaw into a modern residential city modeled on the great European centers of power. At the Warsaw Construction Office, the equivalent of the art department of King Louis XIV, led by architects J. K. Naumanna, J. D. Jaucha and J. F. knowable, three urban and architectural designs were developed: so-called. Saska axis, Kalwaria Road and Aleja Gwardii. Based on French patterns, these projects were of key importance for the city's development. The remains of the Kalwaria Way are the two columns with gilded crosses standing to this day in Plac Trzech Krzyży (from years 1724-1731) and the figure of St.. John of Nepomuk (with 1756 year, chisels J. J. Plerscha).

The times of Stanisław August Poniatowski (1764-1795) przyniosły miastu kolejne nowatorskie rozwiązania. The population of Warsaw reached then 150 thousands, which promoted the city to the group of several largest metropolises in Europe. Thanks to the wealthy financiers, Warsaw gradually transformed into a capitalist city. The most important investment was the new urban axis: King's Road, known as the Royal Route, developed over the years 1768-1773 according to the principles of the Enlightenment. The basis of the new axis was a linden avenue known as the Royal Road, connecting the Royal Castle with the private residence of Stanisław August in Ujazdów. The route had a network of star-shaped squares, characteristic of the planning solutions of that time. Today they are squares: Savior, At the Crossroads, University of Technology and the Union of Lublin. Along the new axis, a number of residences and park complexes were built- palaces, designed mainly by Szymon Bogumił Zug according to fashionable English and French patterns.

In the 19th century, the buildings were built on Aleje Ujazdowskie oraz Aleję Szucha i Aleję Róż, where the first colony in the city was established “Rose Garden” with exclusive palaces of the aristocracy and the Warsaw bourgeoisie. Aleje Ujazdowskie then became the most beautiful and elegant street in the city, Warsaw's Corso, a meeting place for the social elite, described by the then realistic novel. The alleys also have a dark history: here 6 October 1939 year Adolf Hitler received a two-hour victory parade, and its officials transformed the area into a closed German district with the headquarters of the Gestapo and heavy arrest for Poles.

This part of town, little damaged, retained its representative character after the war. The Office of the Council of Ministers is located here, ministries and embassies. The Royal Route is used to describe the communication route along the Warsaw Escarpment from the Royal Castle to the Wilanów Palace. Trasa spacerowa wiedzie od placu Zamkowego do Belwederu. The route is part of the historic city of Warsaw, which in 1994 year was declared a Historical Monument.
