The discovery of the temple’s surviving structures next to the arch of Drusus and Germanic was thanks to Spoletan archaeologist Giuseppe Sordini, who in 1900 started excavating around the temple’s pedestal, the stylobate. The dedication of the temple is still unknown, but the building dates to the 1st century and was one of the main monuments around the Forum, the present piazza del Mercato. It consisted of a rectangular cell introduced by a pronaos, accessible through a staircase that connected the Forum’s floor to the stylobate.
As you approach the square, on the right side of via dell’Arco di Druso you can walk on a part of what was the cardo maximus, with its original Roman paving, next to the temple’s remains, that consist of a trunk of column of the pronaos, of the stylobate and of a carved fragment of marble entablature.
