Templum Matidiae

On the Campus Martius in ancient Rome stood the Temple of Matidia, dedicated to the deified Salonina Matidia. She was the mother-in-law of Emperor Hadrian, who raised her to the status of a goddess after her death in 119. Immediately afterward, Hadrian began construction of the temple on a site near the Pantheon and the Saepta Julia, which he also restored. Later, after Hadrian's own death and deification, the Hadrianeum was built next to the Temple of Matidia. The exact location of the structure is no longer fully certain today, but a piece of lead water pipe inscribed "templo matidiae," found near the church of Sant'Ignazio, points to its probable location.
