Aquincum

Aquincum was the capital of the Roman province of Lower Pannonia and stood where the northern suburbs of Obuda are now. What is open is the civil town: a grid of low wall stubs across an open field, with streets, a market building, bath complexes, a shrine of Mithras and the outlines of workshops and houses, some with underfloor heating still visible. The museum beside it holds mosaics, painted plaster, tombstones and its best object by a distance, the bronze remains of a third-century water organ found in the burnt ruins of a guild building, shown alongside a working reconstruction. Two Roman amphitheatres survive a few streets away and can be walked into without a ticket.

History

The site was first settled by the Eravisci, a Celtic tribe, and the Romans made it a fort on their frontier, the limes; a cavalry unit of 500 arrived around AD 41-54, and by AD 89 the legion Legio II Adiutrix, 6,000 men, was stationed here. The city grew around the fortress, became a provincial capital after the reorganisation of Pannonia in AD 103, served at times as the headquarters of emperors, and had at least 30,000 inhabitants by the end of the 2nd century; Marcus Aurelius is believed to have written part of his Meditations here. Under constant Sarmatian attacks in the 4th century it was largely destroyed by 350 AD (Wikipedia, Aquincum).

The main sights

• The civil town grid - streets, shops, baths and heated floors at knee height.
• The water organ - third-century bronze pipework with a playable reconstruction.
• The Mithras shrine - the small sunken temple within the town plan.
• The amphitheatres - two free arenas in the surrounding streets.

When to go

April to October, when the open-air part keeps full hours; the ruin field shuts or runs short hours through winter while the museum stays open. Mornings are best in summer because there is no shade anywhere on the site. The museum runs Roman craft and food days a few times a year, which are aimed at families and fill the site.

Practical notes

This is a foundations site: almost nothing stands above waist height and you have to build the town in your head from the plan. A busy road and the suburban railway run right alongside, so it is never quiet. Labels are uneven in English. Anyone who has seen a well-preserved Roman town elsewhere will find it thin, and it is a forty-minute round trip from the centre.

Nearby

Obuda's main square and the Roman military amphitheatre are a few stops back down the line.
