Vythos (Greek: Βυθὀς, before 1927: Ντόλος – Ntolos),[2][3] is a village in Kozani regional unit, Western Macedonia, Greece.
Vythos is built at an altitude of 1035 metres, in one of the most steep and isolated areas of Voio, literally into the arms of the mountain.
The huge falls of Skotomeno Nero is situated in the forest besides Mavri Rahi or Mavriaha, an astonishing mountain chain which bonds Vythos to the peak of Prophet Ilias, through old macadam roads.
Behind Mavriaha, following the big crest of the mountain, at an altitude of 1784 metres, is Petritsi - the third highest and most imposing peak of Voio.
The water that comes down from the chestnut forest of “Sioust” is so plentiful that the bigger spring has two pipes in order to best serve the inhabitants.
The “Magianadiko”, “Doumousiariko”, “Giouradiko Mpnari” and “Kerasoftades” springs are situated in the upper part of the village and flow from Karaouli.
Like many villages in Greece, Vythos has experienced significant urban drift as people move to the city where employment is more plentiful.
Significant residents migrated overseas, most prolifically in the period 1940 - 1970, and primarily to New Zealand, Australia and the United States of America.
The characteristic slabs placed on the corners of the buildings on which are chiseled the date of development, the figure of the owner or the master builder or even sacred symbols are there to protect the house and the residents from evil.
The buildings are completed by their yards, which are demarcated by high stone fences and characteristic wooden garden doors.
The garden doors are decorated in interesting designs with big fat pins, and they have their one protective roof made by wooden frame and slates.
The school was rebuilt in 1950 by the Society of the Emigrants to America after it was burned by the Axis occupation of Germans during World War II.
Today it forms part of the trekking path “The Journey of the River Promoritsa”, which begins from the “Monastery” and ends up to the stone-made bridges of Morfi.
Larger than "Leno's bridge" it connects the two sides of the “Karaouli” stream, which often becomes rapid during the heavy winter and spring rains.
The stream bed descends from the chestnut forest “Sioust” and as it is wider due to the soft ground, it results in a bigger bridge arch.
