Early Celtic and Saxon cathedrals tended to be of diminutive size, as is the Byzantine so-called Little Metropole Cathedral of Athens. In Italy, with a few notable exceptions such as Florence Cathedral and Milan Cathedral, cathedrals are numerous and are often similar in form and size to monastic or large parish churches. In modern times, where functionality is the foremost consideration and where church attendance is low in many countries, a cathedral church may be a modest structure.
