Feast of Agios Ioannis o Rosos, Prokopi
26–27 May
The biggest pilgrimage in Evia: the incorrupt relic of St John the Russian lies in the 1951 church at Prokopi, and on 26-27 May tens of thousands come, many walking overnight from Chalkida or Mantoudi, for the vigil and the grand procession of the silver reliquary on the morning of the 27th. The shrine has a 160-bed hostel and a canteen, and the village fills with stalls. Roads into Prokopi are closed to traffic on the day, so park on the Mantoudi side and walk.
