If still in use by the 4th century AD, the temple would have been closed during the persecution of pagans under the Christian emperors.

In the 6th century AD, the temple was largely demolished and a three-naved Christian basilica was built from the same stone on the same site.

The ground plan is almost square (13.29 x 12.73 m), when Greek temples, especially in the archaic period are usually elongated.

The temple was built without a foundation platform (the Crepidoma), directly on top of the euthynteria, likewise there is no stylobate for the columns.

The doorway was decorated with bands lined with a large bead and reel pattern.

Like the facade columns they stand atop smooth Samian bases, but these have no torus.

These columns supported the marble struts of a saddle roof, which ran from front to back about 4 metres in each direction.

This culminated in 1994 in a partial restoration of the structure and the construction of a small museum on the site, which was opened in August 2001.
