Fort Bourguignon (Fort Monsival) is one of many fortresses in Pula, Croatia, which were built by the Austrian Empire in the second half of 19th century. The chief reason for building the fortress was to protect the main Austrian naval port. It was one of the last fortresses built to create the inner fortification rings, forming an arc within a radius of distance in order to protect Pula's port. It was named after the Austrian admiral Anton Bourguignon von Baumberg. The fortress is inspired by the 1820 fortress design of Archduke Maximilian of Austria–Este for protecting Linz, Austria. Pula's fortresses differ from the original Linz fortress in that older fortresses built between the years 1851 - 1855 are smaller and weaker than the ones built ten years later, like Fort Bourguignon.
