The Servian Wall:
          Servius Tullius was credited with the creation of the Servian Wall during the sixth century BCE.  A strong wall of defense, the Servian wall was up toten meters tall and 7 miles long. It had 12 gates, though some believe it to have had 16 gates. The biggest remaining section of the wall stands near Stazione Termini, the main railway terminal in Rome today. It ran along the Tiber River, through many mountain valleys, around the Caelian, and South of the forum Boarium.
          Though credited with the construction, the wall is now believed to have been built during the 4th century BC.

Temple of Diana:
          The Temple of Diana was built during Servius Tullius’ reign during the 6th century BC. According to Roman historian Livy, the creation of the temple was ordered by Servius Tullius  after he learned of the creation of the Temple of Artemis built by the combined work of the communities in Asia Minor.
          A little after the temple was built, an amazing cow was born to a Sabine family, and it was predicted that sovereignty would be given to the city of the citizen who was to sacrifice the cow to Diana. The Sabine took the cow to the Temple, and the Roman priest there told the man to cleanse his hands in the Tiber before sacrificing the cow. As soon as the man left to wash his hands, the priest instantly sacrificed the cow himself, pleasing Servius Tullius.

The temples of Mater Matuta, Goddess Fortune, and Fors Fortuna:
          Servius Tullius also built twin temples to Mater Matuta and the goddess Fortune. They stood in the Forum Bovarium, a market along the Tiber River banks. The main temple of Mater Matuta is in the city of Satricum, South of Rome. The goddess Fortune was represented by a veiled statue, much like the Etruscan Gods of Fate were.
          The temple of Fors Fortuna was built on the other side of the Tiber, outside of the city wall. Slaves would participate in their celebrations there.
