The southernmost of the three Komarom forts, built in the 1870s on the road south to Igmánd. Smaller than Monostor but more compact and easier to take in at a single visit; the casemates now house the Klapka György Museum's collection of Roman artefacts from Brigetio.
The displays cover Roman gravestones, mosaics, glass, and bronze military fittings, plus a small section on the Hungarian War of Independence in 1849 and the building of the fortification system itself. Allow about an hour. Free or near-free entry.
