The Skeleton Heel Stone (骸骨の踵石 Gaikotsu no Kakato Ishi) is a large ancient stone arena featured in Battle Tendency. Situated 10 roman miles from St. Moritz (Switzerland), at the foot of Piz Bernina, it was chosen by Wamuu as the final battleground between him and Joseph Joestar.
The arena is an antique stone circle with a large torch in the center and four pillars surrounding it with only one column along the route.
According to Kars, in ancient times, the victorious warriors of the arena came here to drink the blood of the fallen and feast on their bodies.
In the ancient times, this coliseum was build so the people would look at the stars. Later, it became an arena for deadly fights.
Kars and Lisa Lisa agree to bet the Red Stone of Aja in a chariot race, in which Joseph and Wamuu fight until one dies. After a long battle, Joseph's chariot is destroyed along with Wamuu's and they are both forced to fight on the ground. Joseph's cunning and tricks assist him in defeating Wamuu and emerging victorious.
Piz Berlina Ruins
After the battle with Wamuu, Kars and Lisa Lisa prepare to fight, but in another stage; the Piz Berlina Ruins. Here, Kars deceives Lisa Lisa and leaves her badly wounded, proceeding to use her as a hostage to wile Joseph. Joseph subsequently manages to save Lisa Lisa and 'defeat' Kars.
- The location of the stone circle is a reference to the actual Piz Bernina, the highest mountain of the Eastern Alps.
