Tempio del Divo Romolo

The Tempio del Divo Romolo is an ancient structure in the Roman Forum in Rome. Its preservation makes it a testament to Roman architecture and history.
The circular brick building, with its dome and two side rooms, each featuring its own entrance and apse, was integrated into the Church of SS. Cosma e Damiano in the 6th century. This transformation, which also included parts of the Templum Pacis, contributed to its current good condition. For a long time, it was believed that Emperor Maxentius dedicated the temple to his prematurely deceased son, Valerius Romulus. However, more recent research suggests that the temple was originally built for Iupiter Stator, replacing an older Republican enclosure. A myth tells that Romulus' troops turned back here during the battle against the Sabines after Romulus pleaded with Jupiter for help.
