Hara Zamkavaya, Summit in Navahrudak Region, Belarus

Zamkowa, also called Putsievichskaya, is a hill 324.1 m above sea level in the Ladzeniki rural council of Navahrudak District, Grodno Region, about 3 km west of Navahrudak and 0.4 km north of the village of Putsievichy. It is the highest point of the Navahrudak Upland and of Grodno Region. The hill is built of red-brown moraine loams covered by silty sandy loam, with gentle slopes of 3–7° and relative rises of 20–25 m; almost its whole area is ploughed.

The hill was first protected as a nature monument in 1997 under the name "Pucevičskaja hara" on an area of 85 hectares. On 18 January 2008 it was declared a geological nature monument of republican significance, and on 6 November 2024 its boundaries were changed and its area set at 91.8 hectares. It was studied during local-history expeditions on Belarusian summits between 2005 and 2012.

The hill is also called Pucevichskaya after the village of Pucevichi 0.4 km to its south. Its Belarusian name, Zamkavaya hara, means "castle mountain", though no castle stood here; the ruins of the Navahrudak castle are on a different hill inside Navahrudak, 3 km east. Near that other hill a mound was raised in honour of the poet Adam Mickiewicz.

The hill lies 3 km west of Navahrudak and 0.4 km north of Putsevichy, in Ljadjenicki selsavet. Its slopes are gentle, mostly 3–7°, with relative rises of 20–25 m, and nearly the whole surface is ploughed farmland, so approach along field edges rather than expecting a marked trail.

The hill was first protected in 1997 as "Pucevičskaja hara" over 85 hectares; on 18 January 2008 it became a geological nature monument of republican significance, and on 6 November 2024 its boundaries were redrawn to 91.8 hectares. Almost its entire surface is ploughed farmland, so the summit itself is a field rather than a viewpoint.
