Oslavia War Memorial, World War I memorial in Oslavia, Italy.

The Oslavia War Memorial is a round tower above a flight of steps, with three lower bastions named Prelli, Montanari and Langoris linked by underground passages. The names of identified dead line the walls of the internal circular chambers. A tall black marble cross stands in the central tower, and the crypt below holds the tomb of General Achille Papa and twelve other holders of the Gold Medal of Military Valour.

The memorial was completed in 1938 following the devastating battles along the Isonzo River. It stands as a record of one of the bloodiest fronts of the Great War in this region.

The memorial was built in a mixed Slovene and Italian area, and its fortress-like medieval style, reminiscent of the Totenburg in Germany, was meant to assert Italian permanence. A bell named "Chiara" in the campanile sounds at sunset. In the crypt lie General Achille Papa and twelve other holders of the Gold Medal of Military Valour.

The site is easily reached from nearby Gorizia and offers visitors a broad view from its elevated position on the hillside. Walking paths in the area are clearly marked, and sturdy shoes are recommended since the access involves some climbing.

The memorial's round central tower was built open to the sky, but water penetration damaged the structure. A plexiglass roof was fitted, and in 2016 it was replaced by a permanent polycarbonate covering. The crypt below holds the tomb of General Achille Papa and twelve other holders of the Gold Medal of Military Valour.
