Pannonian Plains

Aquincum was a border town of the Roman Empire for some 400 years, and its museum puts numbers on the garrison: several military bases in what is now Budapest, including a legionary fortress with a heavy infantry unit of nearly 6,000 men. The civil town beside it reached its largest extent at the turn of the second and third centuries AD, with an estimated population of 10,000 to 15,000.

One of Aquincum's headline objects is a correction. The building inscription known as the Drusus stone had been read as key evidence for the Augustan occupation of the province of Pannonia. The museum now states it commemorates the construction of the Óbuda cavalry fort in AD 73 — a different event, decades later. It sits in the permanent exhibition on military life along the Aquincum limes.

Ljubljana's Roman wall carries a completion date, which is rare. An inscription found near Emona's eastern gate, at present-day French Revolution Square, dates a major construction project — most likely the city wall — to between the autumn of 14 AD and the spring of 15 AD. Ljubljana Tourism records the wall as 2.4 metres wide and six to eight metres high, with at least 25 towers and four main gates.

The Roman frontier this route follows and the Roman frontier UNESCO inscribed are not the same line. The Danube Limes (Western Segment) property was inscribed in 2021 under criteria (ii)(iii)(iv), with a minor boundary modification inscribed in 2024, and it runs from Bad Gögging in Germany through Austria to Iža in Slovakia. Three countries, and Hungary is not among them: Aquincum's stretch of the limes lies outside that property.

Tokaj is inscribed, and its own bodies are careful about what for. The regional tourism body records that the region's winemaking culture and traditions have been honoured by inclusion in the UNESCO World Heritage since 2002, and separately that Tokaj was declared one of the first appellations in the world, in 1737. That hedge is the region's own wording. The region runs to around 5,500 hectares across 27 towns and villages.

Tokaj's oldest working room settled a succession. The Rákóczi Cellar was built at the beginning of the 15th century and owned in turn by kings, sovereigns, princes and generals. Its knights' hall — 28 metres long, 10 wide and 5 high on the tourist board's measure — is the largest underground hall of the Tokaj wine region, and it is where the orders elected János Szapolyai king of Hungary in 1526.

Eger is a town built out of its own basement. The town's tourist board gives the length of the cellar system below Eger as 130 km, and records that cellar-cutting rights in the Valley of the Beautiful Woman passed from the bishop to squires in 1774: by 1781 there were 32 cellars there, and now there are more than 150. The first archive document naming the valley is from 1843.

The vine's output is measured in kilos, not hectolitres. Visit Maribor records an annual harvest of 35 to 55 kg bottled in 2.5 decilitre bottles, of which only 100 are filled each year. Offspring of the vine grow in 27 different countries. Beneath the same city runs one of the largest classical wine cellars in Europe, with 2.1 km of underground corridors.

Slovenian viticulture had an assembly before it had an appellation. Burja Estate in the Vipava Valley records the gorska pravda, a gathering of the viničars who worked the vines and the masters who owned them, as a form of organisation that lasted until 1848 — and states it was not known among the Bavarians, the Lombards or the Eurasian Avars.

Maribor's old vine carries a primacy claim, and it belongs to a named body. The Museum of the Oldest Vine records that the vine was planted in the second half of the sixteenth century, that the first known depiction of it dates from 1657, and that in 2004 it was entered in the Guinness Book of Records. The Old Vine House gives the vine's age as over 450 years; the museum's own text says 460.
