There are few street signs in Costa Rica, and even fewer addresses. Just about all addresses are in terms of a well-known building or landmark; often the local Catholic Church, cemetery, or another fixed location. But just to keep things interesting, some addresses are phrased in terms of buildings that may have burned down 20 years ago! It is very common to make reference to landmarks that do not exist anymore, but had became well-known among people.
Our campus address in Costa Rica is: 700 meters east of the Altos School in San Luis. Imagine trying to deliver the mail!
