Mount Athos is not an ordinary Greek sightseeing destination. The forested peninsula in Halkidiki is a self-governing monastic territory within Greece, home to 20 ruling monasteries, smaller sketes, cells and hermitages. Orthodox monastic life has continued here for more than a millennium, and UNESCO inscribed the peninsula in 1988 for both cultural and natural importance. Every journey must therefore be organised as a regulated pilgrimage, with monastic routine taking priority over tourism.
The organised community developed strongly from the tenth century, when Great Lavra was founded with imperial support. Byzantine and later rulers endowed monasteries that accumulated churches, manuscripts, icons, metalwork and archives. After the fall of Constantinople, Athos continued under Ottoman sovereignty and later became part of modern Greece while retaining autonomy. Architecture ranges from fortified coastal monasteries to remote dwellings on steep slopes.
