The urban expression of a memorial is usually exhibited as a sculpture, park, roadway or a tombstone. A good example is the largest cemetery in Detroit, Mt. Olivet, whose mission to serve Catholic burial needs has been the soil of choice for over 400,000 faithfuls. Between 1920-1950, Detroit may have been the largest Catholic city in the US as it was a destination of immigrants from other Catholic communities. Over the past decades the decline of Roman Catholics has forced the cemetery to welcome other Christians to their eternal land.
