Kerameikos is a district of Athens, northwest of the Acropolis, very close to the center. In antiquity the "Inner Kerameikos" was the potters' quarter (hence the name) and the "Outer Kerameikos", which was just outside the city walls, was the place of a cemetery.
Today you can visit the archeological site where you can see the remains of this ancient necropolis. Copies of the most important burial monuments have been erected on the spot where they have been discovered. You can find the originals at the museum on the site, along with other findings from the area.
The site itself is interesting but not spectacular. On the other hand, the rather small museum, is surprisingly interesting as it has several exhibits of high artistic quality.
