Parco Rocolo is a suggestive location immersed in the vegetation adjacent to Piazza Verneuil en Halatte (French city with which Piegaro is twinned), formerly called Misciattelli Park. At one time, the green area was used by the Marquises as a hunting reserve, while today it is a public garden, surrounded by majestic centuries-old trees, equipped to host outdoor events as well. From here the recent pedestrian path winds around the town walls.

Right in the center of Piazza Verneuil-en-Halatte, stands a monument dedicated to the glassmakers and straw makers who carried out their business thanks to the local glass industry.
The work, created by the sculptor Simone Filosi, rests on a circular base and consists of three figures (a man, a woman and a girl), who constituted two of the key roles of the local economy: the glassmaker, represented in the act blowing, and the dressers, a task usually attributed to women, the elderly and children, consisting in the realization of the lining of flasks, bottles and demijohns.
