Count Pier Francesco Orsini (Google auto-translate) was a man much given to melancholy. The premature death of his wife, Giulia Farnese, and other troubles contributing to the decay of the once proud Orsini dynasty, darkened his outlook on life. Like the world-hating Jacques in Shakespeare's As You Like It, he seems to have come to regard the world around him with a somewhat self-advertising disgust. Orsini retreated noisily from the world of human affairs into nature, albeit a nature much improved by art (Google books preview). Those improvements came in the form of larger-than-life sculptures, some sculpted in the bedrock, which populated Sacro Bosco ("Sacred Grove"), colloquially called Parco dei Mostri ("Park of the Monsters").

In the town of Bomarzo in central Italy you will find Monster's Grove, a vast sculpture garden created in 1552 by Pier Orisini to be a unique & astonishing place. The scupltures are quite large, and some are carved directly into the bedrock; as the name might indicate, the subjects are mainly mythical creatures. For centuries, the stone was uncared for, and nature began to reclaim the art, until the 1970s when efforts began to preserve the pieces, and today it is a major tourist attraction, though still privately owned nearly five centuries in.
