After a brief detour to Ostia, I'm once again starting off with my 10 ancient(not-so-visited) Roman sites in Rome.
The Round Temple is a structure that survives in Rome from very ancient times- it is thought that this could have been constructed in the late 2nd or 1st century BC. Of course the structure we see today does not survive completely from its original state 2000 years ago but parts of it are preserved.
The Round Temple is located at a stone's throw from the Theatre of Marcellus, along the River Tiber. It can also be reached from the other end coming from the Circus Maximus. One of the primary reasons why this temple survived intact whilst others were destroyed or built up over was because it was converted into a church. Sometimes the only way to survive is to be flexible.
We do not know the original deity to whom this temple was dedicated- (people think of it as a temple to Vesta- goddess of the hearth) but it is more thought to be a temple to Hercules.Via http://optimusmaximusadventurous.wordpress.com/2012/08/31/the-round-temple-part-iv-of-10-ancient-roman-sites-to-visit-in-rome/
