Otho II Hightower
|Title||King of the High Tower|
|Book(s)||The World of Ice and Fire (Mentioned)|
Otho II Hightower was a King of the High Tower and head of House Hightower. He had the wooden palisades and ditch protecting Oldtown replaced with massive stone walls, thicker and higher than any seen in Westeros in that time, as the city had previously been sacked three times in a single century. Otho's efforts beggared the city for three generations, but succeeded in their purpose of turning back would-be invaders and raiders.
