Rudolfova štola - Královská obora 170 00

The underground tunnel connecting the Vltava and the Royal Fields, today's Stromovka, led the water to the local ponds. Very interesting are the tours of the adit organized occasionally, it is a work far beyond its origins. At its end at Nabřeží kpt. Jarosha stands guard house.

The technical work that powers the ponds in Stromovka was built at the instigation of Emperor Rudolf II. in the years 1584-93. The hand-excavated gallery with a length of 1,102 meters brings water from the above-mentioned Vltava river. It is occasionally open to the public.

An interesting historical and technical matter.

The tunnel excavated between 1589 and 1593 to supply the Royal Game Reserve with water with a length of 1098 meters overcomes the height difference of the Vltava levels of 110 cm. The adit runs about 45 meters below the terrain and today's development of Letná. The ends are lined with bricks, the bottom covered with ceramic gutters. In Stromovka it ends with a brick portal, decorated with a crown, the year of completion of the building (1593) and the initial R (Rudolf II.). There are also preserved four almost forty-meter vents, which were used during construction. One of them can be seen in Čechova street and is covered by a turret, the other then leads to the park in Letná (near the tennis hall). The tower, which can be seen in Čechova street in front of the house co. 16 is a branch corridor from the main shaft no. 2 and it is a modification from 1906. Shaft no. After reconstruction in 1991, the gallery was partially opened to the public on the occasion of the 100th anniversary of the Jubilee Provincial Exhibition in Prague, but was soon closed again due to unsatisfactory technical condition.
