This is a historic site in Isabela. Between 1946 and 1959 Isabela was a penal colony, where prisoners were made build a wall with huge blocks of lava as punishment. The wall is 100 metres long and 7 metres high. Due to the arduous labour and harsh conditions in which the prisoners lived, this site is known as the wall of tears.

A set of stairs provides a bird's eye view of the wall and the surrounding landscape. You can still see the cement foundations of the USA base dating back to the Second World War.
