Fort Solgales

Fort Solgales (ソルがレス砦, Sorugaresu Toride) is a fortress located seven miles northwest of Bernia. It is where Gilthunder of the Holy Knights was stationed before its destruction.

Plot
Gilthunder was in Fort Solgales, when he heard that a child pulled his sword out. He decided to see himself if this was accident or not and borrowed a spear from one of the guards and threw it directly at Bernia. Unfortunately the spear was caught and returned at the Fort by Meliodas, which resulted in the Fort's destruction.
