Basilica Stoa bordered the north side of the State Agora donated to the city by it's own rich citizen C. Sextilius Pollio and his family, it was built in 11 AD.
During it's day it was considered to be one of the most magnificent buildings in Ephesus.
It was built with 2 storeys and 3 Aisles.
Access to the Basilica was obtained by 4 steps from the Agora Area and 2 entrances on either side of the structure.
12 years after it's completion, the city was hit by an earthquake.
During repairs the number of columns was almost doubled to give the structure more strength.
