Vernio's name derives from that of an ancient Roman winter camp (castra hiberna) located here. A Roman bridge existed in the area, but was destroyed during World War II.
In the 12th century it went from the Carolingians to the counts Alberti from Prato, who lived here after 1107. In the 13th century it went to the Bardi family, as the seat of a county which remained independent until 1798, when it was abolished by Napoleon. After the Congress of Vienna it was annexed to the Grand Duchy of Tuscany.
On 7 June 1944 an American B-25J mitchell bomber was shot down by German anti-aircraft fire over the hills of Vernio. With four 1,000 pound bombs on board, the plane erupted and crashed in the Carbonale woods, in Poggiole, Vernio. Six of the seven men on board perished. The sole survivor parachuted out of the plane and hid in the mountains before making it back to allied lines in Florence three months later. The fallen crew were buried in the cemetery in Montepiano shortly after the crash, their final resting place at Fort Sam Houston, Texas, USA.
In the winter of 2013, the pilot's military tag was found in the woods, and brought to the local museum. The museum hosts an exhibit of the B-25J mitchell consisting of parts of the plane found through metal detecting and also donated by locals. A monument at the crash site was built by the museum and unveiled at the 70th anniversary memorial event on 7 June 2014. A book was written about the crew and events surrounding the incident, presented at the city hall in downtown Vernio also on the 70th anniversary.
