This
was on the north side of the street. According
to one inscription, it was built around 102-114
AD in the name of the Emperor Trajan. The altar
inscription is on a piece of the cornege beside
the fountain. The fountain had two-storied
columns on three sides. Between the columns were
statue niches. In the central niche was a statue
of Trajan. Water entered the fountain through a
pipe under the emperor's feet. The original
height was 12 m, but was reduced when later
repaired. Statues found here of Dionysius, a
satyr, Aphrodite and the royal family are on
display in the Museum.
