The County Museum of History and Art (Romanian: Muzeul Județean de Istorie și Artă) is a museum in Zalău, Romania, established in 1951.

In 2015, a stone sarcophagus was discovered during restoration of a sacred area at Porolissum.

The find was unusual because the sarcophagus was not in the cemetery that had been previously excavated.

The sarcophagus contains skeletal remains of a young peron, and the limestone lid has carvings that were common in Roman times.

A hole in the lid suggests that the grave was robbed in antiquity.
