Piazza della Minerva is a piazza in Rome, Italy, near the Pantheon.

Its name derives from the existence of a temple built on the site by Pompey dedicated to Minerva Calcidica, whose statue is now in the Vatican Museums.

Facing this piazza are: From the 17th century, the convent became the base of the Roman Inquisition or Holy Office, and it housed the trial and recantation of Galileo Galilei.

Little remains of the Dominican complex except its cloister: This had been largely rebuilt from the original building, and expropriated by the state in 1870 as the seat of the Ministry of Public Education and for a short time the Ministry of Post and Telecommunications.

The cloister now holds the library of the Italian Senate, dedicated to Giovanni Spadolini.
