The large Jewish cemetery in Ostroh has a steep slope on its northern and eastern side with a 45 degree gradient. The site had been fenced, gravestones placed in their original positions and was fully renovated and an original brick fence surrounded the western part of the cemetery with concrete panels on the north and east sides. Fencing on the southern side was of wood and concrete. The site has an Ohel and a Holocaust mass grave on its territory. ESJF surveyors noted in summer 2015 the unlawful interference of a neighbouring owner which had destroyed the natural relief of the cemetery, causing the collapse of the original fencing on the eastern side and exposing graves and tombstones. The ESJF constructed a concrete supporting wall of some 100m to protect and extend the original fencing. Works at the site were completed in September 2015.
