Archaeological Site
Qohaito
Historians debate whether or not the ruins of Qohaito were once the inhabited walls of the ancient town of Koloe, a settlement that predated, but grew to commercial importance during, the Aksumite kingdom. Even if it wasn't, the city's impressively large remains – covering an area of 2.5km (1.5mi) by 15km (9mi) – are testament to its once-great stature. Though only about 20% has been excavated, it'll still take you a few hours to make it through the main sights.
