It is the largest non karst lake and the third biggest natural lake in Slovakia. It is at an altitude of 618 m, covers 0.13 km² with a maximum depth of 25.1 m. It is drained by the river Okna. The oldest known description of the lake can be found on two maps, dating back to 1687. The earliest official name of the lake known as Blatné jazero (germ. Blatto teich) dates back to 1784. The name Veľké Vihorlatské jazero was introduced in 1933. The lake itself is a natural home to 8 species of fish. The native species consist of the brown trout (Salmo trutta m. fario), common minnow (Phoxinus phoxinus) and stone loach (Barbatula barbatula).

The Chapel of Virgin Mary is a neoclassical building situated in the only cemetery in Snina in Slovakia. The chapel was built by Štefan Rholl in 1842. Because his family had roots in Snina, he built a tomb with a chapel for his deceased relatives. A former cemetery, which existed on the decline created by the backing-up of the river Pčolinka, was not suitable as Pčolinka posed a threat when it flooded. The roots of Rholls in Snina went back to 1799 when the businessman Jozef Rholl bought the lordship of Snina from the sons of countess Terézia van Dernáthová, an important event in Snina's history. Jozef Rholl came from a family which worked with metallurgy in Gemer and Spiš. In 1809, Jozef Rholl built iron-works with attached walled houses for the workers. Under the chapel was the family tomb of Rholl, which was robbed during World War II. On a wall inside this chapel, this legend in Hungarian is well preserved: Here lies Katherine, wife of respectable and courageous Jozef Rholl, born Uszfalvai. She sleeps forever since the day of Saint Michael in the year 1803, in the 55th year of her life. With thanks and deep regard from her son Stefan, built in 1842.
