The ancient Roman festival honoring the goddess Vesta that was held in June, near the summer solstice, was Vestalia.
Vestalia was a Roman festival dedicated to Vesta, goddess of the hearth, home, and family. It ran from June 7 to June 15, with June 9 as its central day. During the festival, Roman matrons were allowed to enter the usually restricted inner area of Vesta’s temple in the Roman Forum.
Women brought offerings connected with the household and domestic life, while the Vestal Virgins maintained Vesta’s sacred fire. Vestalia was not the same as a general Roman summer-solstice holiday, but its June timing places it among the ancient seasonal observances associated with midsummer. The festival ended with the temple being swept and ritually closed.
