Before the 2011 local government reform, it was the largest municipality in all of Greece, covering an area of 873.552 km2 (337.28 sq mi).

The area has several features to attract tourists: the ski center of Falakro, the traditional settlement in the village of Granitis (pop.

55), the historical bunker of Lise, the artificial lakes of Lefkogeia and Potamoí, the spectacular routes in the forests, the old churches.

In 1927, its name was changed from Ζύρνοβο (Zyrnovo, Зърново) to Kato Nevrokopi,[3] after the neighbouring town of Nevrokop was renamed Gotse Delchev.

On 18 April 1945, during fighting related to the Greek civil war, many Slavic Macedonian inhabitants left the area.
