 The entrance was preserved as late as the 16th century, but the keystone of the lintel had slid following the 1759 earthquakes; a column of rough masonry was erected in the 1860s or '70s to support it.The earthquakes also damaged the area around the soffit's famed inscription of an eagle, which was entirely covered by the keystone's supporting column.Some historic Roman coins depict the structure of this temple along with Temple of Jupiter.
