Most of Erekle II’s 4km defensive wall still stands, with 23 towers and each of its six gates named after a local village. Part of the wall runs along Chavchavadze on the hilltop on the northwest side of town, where you can enter the tiny Stepan Tsminda Church inside a tower. Another stretch runs down beside Gorgasali on the northeast side of town. Here you can climb up inside one tower and walk atop the walls down to two more.
