Didivska lake is a remnant of the Black swamp Machar, on the site of a former sand quarry. The name comes from the village of Diyda (former name – Dedovo), which is located a few kilometers West of Beregovaya. Old-timers claim that a huge black snake with a long neck and a thick body lives in the lake. Based on this description, we can make the assumption that the diedivske monster is a relative of the world-famous monster from the Scottish Loch ness. According to local residents, earlier during night bathing on the lake, people often disappeared without a trace, and these victims were attributed to a mysterious snake. However, no such cases have been recorded in recent years.
In summer, lake Dyda is a favorite holiday destination for Transcarpathians and guests of the region. There is a sailing center on the lake, a cafe and a medical center

Arpad's great-grandson, Prince Geiza, converted to Christianity and raised his son Istvan in the Christian spirit, for which he invited German missionaries. The wife of the young Istvan was the sister of the Bavarian king gisella (and herself, whose statue adorns the building of the music school in Uzhgorod).
Istvan I the Saint continued the work of Arpad, consolidating the Hungarians into a Christian power.
