The inner propylon, built in the mid-second century AD, was a monumental gateway leading from the outer sanctuary (the excavated area, centring on the Temple of Triptolemus) to the inner sanctuary centring on the Temple of Demeter and Kore, which was closed to non-initiates. The foundations of this structure have not been excavated, but fragments of the masonry and sculpture have been found in the excavations and reused in the [[Little Metropolis]].{{sfn|Miles|1998|pp=89-91}}

The fragments closely parallel those from the inner propylon of the sanctuary at Eleusis, which provides the basis for a reconstruction.{{sfn|Miles|1998|p=89}} The main sculptural fragments are two caryatids, which would have stood on the inner side of the gate, supporting a porch.{{sfn|Miles|1998|p=90}} A Doric frieze on the outside of the gate consisted of [[metope]]s and [[triglyph]]s with Eleusinian symbols ([[poppy|poppies]], [[myrtus|myrtle]], [[plemochoe|plemochoae]], [[Patera|phialae]], [[bucrania]]).{{sfn|Miles|1998|pp=89-90}} Parallels between structures at Eleusis and in the city of Athens are typical of those constructed under Hadrian, part of "an imperial Athenianisation of Eleusis."{{sfn|Miles|1998|p=91}}{{sfn|Clinton|1997|p=175}}
