The building originally stood on a crepidine of three steps and had a tetratislal marble pronaos. During the imperial age it was transformed into a Capitolium. After the Jewish revolt, the marble pronaos was rebuilt, which was deeper than the previous one and punctuated by four Doric columns with Ionic bases, and covered the krepìs with a staircase that encompassed the front of the monument on three sides. Access to the temple was provided by two steps on either side of the pronaos. They served to conceal the original krepìs.
