Google satellite view of modern-day Benin City shows clear evidence of past earthworks in the countryside surrounding. In particular traces of an earthen structure runs northeast out of the city starting at about St. Savior Rd, through Urhokuosa, Erua and Ethor to Irrua. A distance of 50 miles, and perhaps further.

Wow, that city has one of the best visible-from-sky modern artifact collections I've seen:

The way those artifacts gradually start to blend with the greenery is fascinating. It'd be fun to play there as a kid I'll bet
