Eichen House
The mental hospital where William Barrow was being kept. Established in 1912.
Lydia felt that Stiles was in the basement of Eichen House, although they did not find him there. The basement in his dream looked like the Eichen House basement, however, and the actual basement had the onore kanji carved into the wall.
Eichen House has an additional underground ward that houses the supernatural. It's made with mountain ash wood and reinforced with telluric currents. Eichen House is built on the convergence of two currents. It was able to keep the The Dread Doctors out until Kira disrupted the currents with her lightning power.
It is currently housing Valack, Peter Hale, a slaugh, and host of other supernatural creatures.
