This courtyard formed the atrium of the Cathedral (in the background) and was surrounded by a portico of columns on all four sides. It was nearly square-shaped, before being cut into on its western side for the construction of the apse of the church dedicated to St. Theodore.
The courtyard is particularly notable for the hard limestone paving that covers its entire surface and the beautiful square basin that adorns its center, which earned it the name "Fountain Court". Decorated with several carved blocks, many of which were reused from coffered ceilings taken from the monumental altar of the Temple of Artemis, this installation underwent several changes and improvements. However, it is not clear what the original form of the courtyard was prior to the construction of the Cathedral around 450/455 AD.
