Volcano

Jail

The tiny Volcano Jail looks to be under the gun here, but this monitor is no longer loaded. Although the jail seems hardly able to withstand a strong gust of wind, let alone hold dangerous criminals, it proved its worth many times. Built in 1872, the secret to its success are the metal plates sandwiched in between the wooden planks which form the walls. The jail is virtually escape proof, and the story goes that its first prisoners were the men who constructed it.
