Ceriadae or
Keiriadai () was a
deme of
ancient Attica, of the
phyle of
Hippothontis, sending two delegates to the Boule.
It was located outside of the walls of
Themistocles, west of the hill of the Nymphs and west of the
Pnyx. In this deme there was the baratharon (βάραθρον), a chasm into which criminals condemned to death were thrown.
The site of Ceriadae is west of the Pnyx.[
