The hostel where we are staying was a building constructed by Austro-Hungarian soldiers in 1882 and used as a military prison until 1991. A group of artists, architects, and scientists from the Culture and Art Association decided to transform the building. More than eighty Slovenian and international artists participated in the Celica project, which started in 1993. First they had to prevent the building from being destroyed by sprawling their bodies in front of it to save it from the wrecking ball. In 1996, the building was named a historic landmark and is now protected.
The project was a work in progress. Each prison cell was turned into an art piece independent of the others. It has been open to the public since 2003. They offer free tours at 2 pm every day. I suggest if you book here, try to get a room from 101 to 110. They are on the quieter side of the building. Inside the hostel is pleasantly quiet, but if you need a window for air, the artist colony next door is extra rowdy.
We would highly recommend it for cleanliness, service, and overall appearance. Being that we are both tall, the beds are a bit short for us, but otherwise it is quite nice. We would definitely return if we were to come back here.
