The current arrangement of the Freedom Square (Námestie slobody) is from the 1980’s and buildings around of functionalistic style are also a heritage from the communistic era. Important events were taking place on this square in the past. The Slovak inventor Ján Bahýľ in the year 1897 took off on the world’s first helicopter. The dominance of the square is Družba Fountain, which is the largest fountain in Bratislava. The core of this stainless steel artwork is the linden flower which is a symbol of Slavs. The flower itself is 9 m in diameter and is the centre of the circle which is 45 m in diameter. The original cascading pools surrounding the fountain have a difference of 2.5 m.
