The cache is hidden close to a landmark on the top of a hill in Kraków.
Between 1820 and 1823 a 34-metre high mound was raised in memory of the Tadeusz Kosciuszko, who led an army of peasants to victory in the battle against the Russians at Raclawice.
An Austro-Hungarian fort was later constructed surrounding the mound, and today the place still has a special feeling connected to it. Although parts of this fortress are now in ruins, it contains a Hotel, the headquarters of the Polish radio-station RMF-FM, a cafe, restaurant and two museums.
From the top of the mound there is a great view of the city and although most tourists never go here, it is a must-see in Kraków.
The easiest way to reach the mound is by bus #100 from Salwator or #101 from Os. Podwawelskie or Rondo Grundwalskie. However, it is much nicer to walk from the city-centre.
