Don't ask me how to pronounce the name Brhlovce, but it is not only unique in it's name, but also in a number of its houses: the cave dwellings.
The rocks in Brhlovce largely consist of volcanic tuff: it's light and easily worked, but strong. Over the years several houses were cut in the cliff: it was very cheap real estate and ... the temperature in the rooms is a constant 17-18 degrees Celsius, in winter and summer (and it is not a warm region, the average in January is -1 degree Celsius, which equals 30 degrees Fahrenheit). You can read all about the cave dwellings here.
And the butterflies ? Well, for some reason they all gathered at a certain place in a nearly dried up little stream.
