The Templar Cave, locally called the Sea Eye, is located on the top of the Black Mountain in Vynohradiv. It got its name because part of it has recently been filled with water. Attempts by local historians to pump out the water have been in vain – the groundwater does not want to leave. Researchers still don’t know when and by whom the Chorna Hora cave was carved. They agree on only one theory – it happened approximately in the fifteenth century.
