Answer
Ravenna served as Odoacer's refuge during Theodoric's invasion. This fortified city, located in northern Italy, provided a strategic stronghold for Odoacer to resist Theodoric's advancing forces. Ravenna's strong defenses, including its massive walls and moat, made it a formidable obstacle for Theodoric's army. Odoacer held out in Ravenna for several years, but ultimately, Theodoric's superior forces prevailed, leading to Odoacer's defeat and the end of his reign.
