Detail pôdorysov dvoch z opevnení na katastrálnej mape Petržalky z r. 1856 (mapa č. 10 v prílohe), indikované hlavne priebehom hraníc jednotlivých parciel.This paper examines almost unknown fortifications built to defend strategically important Bratislava´s bridgehead in Petržalka. Interpretation of the 18th – 19th historical maps combined with literary data allows to recognise 3 stages in development of redoubts and earthen embankments, which were most likely first constructed in 1682-3. Remnants of originally eight modest-size redoubts, linked with 2 km long embankment, were during the Napoleonic war (1809) rebuilt by Austrian military into 6 larger, polygonal-shaped earthen outposts. Eventually, during the revolution in 1848 two of them near the Vienna highway were repeteadly strengthened by Hungarian Honvéd Army. Their remnants survived until today.
