What is worth visiting in Greece?
From the link https://aktis.guide/en/excursions/43-meteora-monasteries I found what Aktis recommends that you visit Meteora Monasteries. It is a mountain monastery complex that looks very beautiful. This place has been around for a long time and has been pleasing many people. For tourists, it is the best place to see Greece in its historical form. So I definitely advise you to visit it!
