The prints of Salvador Dalí, one of the greatest artist of the 20th century, will be exhibited in the Heritage Museum of Rovinj, from April 25 till October 5, 2014.
The cache is located roughly 250 m from the museum.
Near to the cache there is a wunderfull view of the old town of Rovinj. You can take pictures there - probably in less surrealistic style than Dali. 
Happy hunting
