Leten", originally called "summer camp" or "place to sunbathe" gained its importance in the Middle Ages, when the first military camps were located there due to their strategic location.The areas were mainly vineyards and gardens. It was not until the end of the 19th century that it began to be systematically colonized. Over time, the plains of this area of the city became a place of meeting, entertainment and recreation.
In 1955, a large monument to Joseph Stalin was erected at the edge of Letná Park. This statue was destroyed in 1962 and the Prague Metronome now occupies the site.
During the Velvet Revolution, a plain next to the Letná Park (Letenská pláň) was the site of some important demonstrations against the Communist government. On the 25th and 26 November 1989 approximately 750,000 people protested in here.
