 Only fragments of the town wall and its ten towers remain; these include the south wall of the cemetery and portions of the wall around the church, and two remaining towers in Turmstraße and Bollwerkstraße at the east end of the formerly walled area.The "Obere Bollwerkturm" was converted to a residence in 1919 with a half-timbered addition.The so-called "Steinhaus" in Mühlstraße, dating to 1585, is one of the oldest buildings in Ilsfeld.
