The Sacra Via: from the Colosseum

 
A remark by Varro implies that he considered the Sacra Via to begin in the Colosseum valley.  A century before the construction of the Flavian Amphitheater (popularly called the Colosseum today), he remarked (de Lingua Latina 5.47) that the Sacra Via started from a little shrine (sacellum Streniae) in the Colosseum area and climbed to the top of the Velia (where the later Arch of Titus, showing below, became the entrance to the Sacra Via proper), even though general habit at the time was to use the term only for the descent from the top of the Velia (where you see the Arch of Titus) and beyond down into the Forum.
 
This view is from high in the Colosseum looking west toward the Arch of Titus. 

From here, from the now uncertain site of the sacellum Streniae, the via climbed the Velia, reaching the summit near the Arch of Titus; this stretch was known as the summa Sacra Via.   From the Arch of Titus it entered the Forum.

From the little shrine to a goddess of health named Strenia, or possibly from a bit farther east from something called the Carinae, "keels", a large structure (oritur caput sacrae viae ab Streniae sacello).
 
In later times, after the sacellum Streniae was long gone and the Colosseum was the major landmark, Domitian (late first century CE) built a fountain known as the Meta Sudans, the conical core of which still exists east of the Colosseum and which became the eastern terminus of the Sacra Via.

More modern buildings have obscured the Republican layout between the Colosseum and the Arch of Titus.

On the Velia, near the end of this stretch, Varro again referred to shrines,

At the summa Sacra Via, the part beginning at the top of the Velia where the Arch of Titus now is at the end of the stretch pictured above, was When the Arch of Titus was built by Domitian to honor Titus' destruction in 70 CE, the path of the Sacra Via changed to go a little further to the south through the arch.

There was also an early shrine to Mutunus Tutunus, a fertility deity.
