Bratska mogila, Borisova gradina, War memorial in Borisova Gradina, Bulgaria.

Bratska mogila is a memorial in Borisova Gradina park consisting of a 41-meter obelisk flanked by two lower side sections. In front stands a bronze sculpture of a male and a female partisan; on the right, a mother sends her son to the front, while on the left a worker, a peasant woman and an intellectual symbolize national unity. A granite slab and bronze wreath cover the ossuary.

The memorial was unveiled on 2 June 1956, the day Bulgaria commemorates the fighters who died for freedom and the death of Hristo Botev. Its ossuary holds the remains of 17 Communist Party and Workers' Youth Union activists from Sofia, among them Anton Ivanov, Yordanka Nikolova-Chankova, Vlado Trichkov and Lilyana Dimitrova, killed for their part in the 1941–1944 resistance. During the communist years the park was renamed Park of Freedom; the old name was restored after 1989.

The monument's name means "Mass Grave". Its side groups show a mother sending her son to the front on the right, and a worker, a peasant woman and an intellectual on the left, standing for national unity. The bronze wreaths on the obelisk and the granite slab over the ossuary are the details to look for.

The site is easily reached via nearby metro stations and sits within a section of the park that has good pathway access. You can visit as part of a walk through the southeastern portion of Borisova Gradina, where other routes connect to the memorial.

The monument's full name, Bratska mogila, means "brother's grave". During the communist period (1945–1989) it gave its name to the whole park, which was then called Park na svobodata (Park of Freedom); the old name Borisova gradina was restored after 1989.
