The caves in the hill Květnice are not extensive; however their beauty has attracted a lot of interest. The caves Pod Křížem (Under the Cross) and Květnická propast (Květnice Abyss, 76.5 metres deep) are the well known caves in the hill.
When we descend into the depths of the King’s Cave (Králova jeskyně) discovered in 1972, we will find charming unique fantastic shapes of various dripstones as well as other crystalline forms that Nature conjured up here in the past millennia. Some dripstones look like long pieces of straw up to 160 cm long. Some of the cave parts are so bizarre that they are closed even to cavers.
One of the most valuable discoveries made in 1984 include the part called Dobišarova jeskyně (Dobišar’s cave) and a new part a few hundred metres long found after hard work in 1989. This subterranean place is dominated by the Tišnov Cathedral of respectable dimensions: the length is 35 metres and the width 18 metres.
The cave Pod Křížem (Under the Cross)
This cave was discovered by chance during barite mining. It is a horizontal karstic channel without dripstones. The interesting features in this cave are the calcite cellar decorated with calcite crystals as big as 16 centimetres of a yellowish honey colour and the 10 metre high calc-sinter waterfall. All the decorations in this cave were unfortunately totally damaged by vandals. Therefore the Tišnov cavers sealed and closed all three entrances to the cave in 1984 except for one opening that was equipped with a lockable grating. The aim was to restore the cave to its original natural conditions as the mining tunnels dug over the cave made it an artificially dynamic hollow which dried up. The cave also had to be cleaned of man- made materials, mostly tins which were left behind by the hikers who sought shelter in the cave. It has been quiet around the entrance and in the cave in the recent years so that even the bats came back. The cave is believed to be linked to the King’s cave (Králova jeskyně).
The Květnice Abyss (Květnická propast)
This abyss situated in the western slope of the hill Květnice was also discovered during exploratory tunnelling through rock containing barite. The abyss constitutes a typical partially karstic limestone rift. The rift’s width ranges from a few centimetres to two metres. The depth of 76.5 metres makes it one of the deepest abysses in the Czech Republic. The deepest accessible bottom is filled with stones. This tectonic rift continues deeper down, however it is so narrow that it is impossible to pass through. However it is possible to go in the horizontal direction as far as 30 metres. In 1984 the pithead was secured with a grating. Later on it became clear that not all the possibilities have been exhausted. A previously unknown filled up part was removed and a new side branch tunnel was discovered. The existing depth has not been surpassed; however since 1987 there have been many questions left unanswered regarding the unexplored and dangerous area.
The King’s Cave (Králova jeskyně)
This cave was discovered by chance on 28th July 1972 in the south-eastern slope of the hill Květnice and was named after Alois Král, the honorary citizen of Tišnov and discoverer of the Demänov Caves in Slovakia. The cave has many nooks and crannies and is rather extensive. After mapping the cave, the known part measured 350 metres. The upper floor is placed horizontally about 10 metres under the surface and has been moulded by corrosion and erosion. It has a rich stalactite decoration made up of dripstones of various length and thickness with two calc-sinter lakes of an area of 5 metres. The cavers’ work resulted in smaller discoveries in 1974 with the following discovered formations: Rotunda, (Rotunda), Caving Chimney (Závalový komín), or Lost Chimneys (Ztracené komíny). The abysses and the lower part of the cave are less decorated; however the calc-sinter coatings and waterfalls are more massive than in the upper part.
In 1976 - 77 a new tunnel was dug out providing access to the upper floor in the cave. The long-term and conscientious work of the speleologists was gradually rewarded with discoveries of further parts in this cave complex. In 1984 Dobišar’s cave was discovered with unique decorations in the shape of straws up to 160 centimetres long. Five years later it was found that the cave continued deeper down inside the hill’s rock and two other caves were discovered: The Sinister Cathedral (Hrozivý dóm) with dimensions 20×14 metres and the Tišnov Cathedral with dimensions 35 ×18 metres. The channels, chimneys and tunnels filled up with scree and terra rossa that can be found in some prospective areas, indicate that further discoveries can be made in future. At the moment after the mapping, the cave is about three quarters of a kilometre long; however the issue of this karstic phenomenon has not been completely sorted out yet. There are still many questions left that require an answer. Only the fact that the water surfaces of the brook Besének and the river Svratka are situated around 120 metres under the lowest accessible place in the cave is for the scientists a challenge giving them no rest. However theory has to be proved to be true by consistent and hard work and by palpable evidence. Those cavers who started the discoveries in 1972 have grown old and try to pass their experience on to younger cavers who, let’s hope, will not only carry on the work and discover new places but also protect this unique countryside.
