Őrjeg raised from a one-time branch of river Danube (Sár, Turján, Red marsh) as a boundary of eastern land created a closed area, which probably is the same as 'Big Island' written by Anonymous and stayed by princely dynasty.
Nowadays only geographical names of the village boundary remind us of the old water world.
After 1945, the infrastructure of the village improved a lot (electricity, kindergarten, library, flats, artesian well, and groceries).
From 1954 till 1973, several folk music researchers and collectors visited the village.
Őrjeg - with its peateries, pastures, grasslands almost on 1000 - was pronounced a nature conservation area in 1997.
