Assisi, Umbria, Italy. Temple of Minerva housing the church Santa Maria sopra Minerva.

The Temple of Minerva (Italian: Tempio di Minerva) is an ancient Roman building in Assisi, Umbria, central Italy. It currently houses a church, Santa Maria sopra Minerva, built in 1539 and renovated in Baroque style in the 17th century.
The temple was built in the 1st century BC by will of Gneus Caestius and Titus Caesius Priscus, who were two of the city's quattuorviri and also financed the construction. The attribution to the goddess Minerva derives from the finding of a female statue, although a dedication stone to Hercules has been found, and the temple was likely dedicated to this male semi-god. In the Middle Ages the temple housed a tribunal with an annexed jail, as testified by one of Giotto's frescoes in the St. Francis Basilica, which portrays the church windows with bars.
Of the ancient temple, the façade has been preserved, with six Corinthian columns supporting the architrave and a small pediment. The columns were originally covered by a very strong plaster, which was perhaps colored. The cell was completely demolished during the church's construction, in the 16th century, while a small section of the temple was found in the 20th century near the altar.

The temple was visited and described by the German poet Goethe during his travels in Italy, as the first ancient structure in good condition seen during his life (1786).
