Next interesting thing is ice sculpture festival which starting in January every year and it will be for few weeks. You can see there so many (maybe 15) ice sculptures, but one thing is so bad. You must count with There is so so cold and so windy.. When i was there it was there -15°C and so windy. That day i thought is my last one. But not i am still here and preparing this for you and you will be next one who will try how cold it can be in Czech.
