Absolutely BEST possible Level 6 Town Hall in the game Clash of Clans. With this base design, the walls are two-layered on all sides. The enemy attackers will waste all their time on the walls, and if they were to penetrate the inside, then they will be attacked by ALL your troops because they are all within the reach of the center. Mega bombs on the outside will destroy any initial mass attacks too.
Video shows 4 attacks and all failing because of this strong defensive structure. The Town Hall is protected by double layers of walls, and the Wizard, Archers, Cannons, etc are all surrounded by walls. This is the best you can possibly do.
