An educational festival of architectural design and art installations.  Take a walk in Prague 3 and keep an eye out in the area as you will be able to see interesting creations in various parks and other public spaces that deal with the environment and architecture.  Part of the idea is to place art in dilapidated areas to gain public interest and awareness so that these areas can be developed in the future.  Go to the website for information on which parks and spaces you can find the artwork and also for information on the dates and times tours and workshops are offered.
