The area of the square existed as early as in the Middle Ages. It was named after Joseph Jungmann in 1878, when his statue was placed there. In the middle of the square there is a block of two historic houses and behind them a cubist column with a lantern which is a unique piece of Czech cubist architecture. It was built in 1913 according to the design of the architect Vlastislav Hofman. The dominant feature of the square is the Church of Our Lady of Snow, part of which is the publicly accessible Franciscan Garden. The Adria Palace stands at the corner of Jungmann Street and the National Street. The palace is built in the rondo cubism style according to the project by Josef Zasche and Pavel Janák and is an important architectural monument. Leading Czech sculptors assisted in its decoration.
