Single and alone houses and communities created at the beginning became merging. Settlements, villages and farm places were joining together untill a real city (the first Prague city) appeared in front of the Prague Castle. Ramparts surrounding the entire city protected it against aggressions. The present-day Lesser Town dates to the 13th century, when it was established by the king Přemysl Otakar II. And so the growth of the city continued; more and more new inhabitants and settlements moved in to this part of the country, as if it was created for a peaceful life without interrupting.

The city part Hradčany was created in the 14th century, and then the New Town saw the light of day. Prague was spreading to all sides and absorbed smaller villages, houses and market halls as if it was a famished dragon. In the 18th century, the Jewish Town was also incorporated. At that time, this part was named “Josefov” in honour to the name of the Emperor. In the 19th century, Prague suburbs were changing into autonomous cities. Then came up a time when a young and relatively inexperienced teenage become a full-value member of the family. Settlements became cities, which wanted to merge with their “mother”. For the long time, the biggest obstacles in doing so were the city ramparts, which were set to save the city of Prague against enemies. After all, this problem was solved and so the time-honoured Vyšehrad, Holešovice and Libeň could join the city of Prague in 1883.
