There is no castle in Drama. But there are remains of the Byzantine walls of the city which until recently were completely neglected and sidelined. Several sections are preserved in the northern quarter of the city, around the church of Agia Sophia. In addition, there are other sections inconspicuous and scattered throughout the city, in house yards, in shelters, etc. It is characteristic that in Drama, very often, parts of the wall serve to demarcate properties!
