Celemantia (or Kelemantia; the modern name of the site is Leányvár) was a Roman castellum and settlement on the territory of the present-day municipality Iža (Hun: Izsa), some 4 km to the east of Komárno in Slovakia. It is the biggest known Roman castellum in present-day Slovakia. It was a part of the Roman limes, the frontier-zone of the Empire. A Germanic settlement "Celemantia" in this area is mentioned by Claudius Ptolemaios in the 2nd century AD. It could be identical with the remnants of a civil settlement found next to the castellum or with another unknown settlement or, as some historians assume, it is the name of both the castellum and the remnants of the civil settlement. The construction of the castellum started in the 2nd half of the 1st century. It was conquered during the Marcomannic Wars (166–180) and burned down by Germanic tribes, and was rebuilt later. It ceased to exist around 400 (beginning of the Migration Period). The ruins were very well visible up to the late 18th century, but afterward people used stones from the constructions to build the fortress and other buildings in Komárno. According to a local legend, a Roman soldier, Valentin, kept his mistresses in the fortress. The fictitious story explains the origin of the name Leányvár, meaning Girl Castle in Hungarian. However, the name probably refers to the fact that the ruins of the castle were donated by King Béla IV of Hungary to the Dominican nuns of Margitsziget who later built a small fortress among them. In July 2021, Celemantia was added to the UNESCO's World Heritage List as part of the Western segment of the Danubian Limes of the Roman Empire.

The Battle of Hetény, fought on 5 September 1849, between Hungarian Hussars led by General György Klapka and a Russian detachment of Cossacks was one of the last battles of the Hungarian War of Independence. After the surrender of the Hungarian army led by General Artúr Görgei at Szőlős, one of the last strongholds of the Hungarian independence was the fortress of Komárom, which now was being surrounded by Austrian and Russian troops. The small reconnaissance unit of Hungarian hussars which tried to acquire knowledge about the enemy's strength, was attacked by a platoon of Russian cossacks, but the Hungarians defeated them, using the tactic of feigned retreat. These kind of small scaled battles and skirmishes between Hungarian troops with the Austrian and Russian besieging units continued until the surrender of the fortress of Komárom on 2 October 1849.
