Város a város alatt, Underground museum in Eger, Hungary

Város a város alatt is a museum in a section of Eger's cellar system, entered at Városfal utca 1 through the former Gyertyás Borok House. The roughly 4-kilometre network once ran from the Hatvani Gate to the Rác Gate. Its passages were cut into rhyolite tuff quarried from the hillside behind and beneath the bishop's palace.

After the Turks left Eger in 1687, Bishop György Fenessy chose not to rebuild the Gothic palace in the castle and instead had a new palace built on two plots in the town. The riolite tuff for it was quarried from the hillside behind and beneath the palace, leaving a cellar system about 4 km long that ran from the Hatvani Gate to the Rác Gate. It stored the tithe of wines from vineyards between Gyöngyös and Munkács, worth 10–13 million litres a year to the bishopric. Unused after nationalisation in 1947, it was reinforced with reinforced concrete in the early 1980s.

The name refers to the cellar system beneath Eger's streets, entered through the former Gyertyás Borok House at Városfal utca 1. The roughly 90-minute guided walk first presents the cellar's past and present, cellar construction, grape growing and winemaking, then introduces period trades and professions as a kind of time travel.

The entrance is at Városfal u. 1, through the former Gyertyás Borok House. Tours run hourly and last about 90 minutes. The cellar stays at 15–17°C all year, so bring a sweater or jacket.

In 2007 a public vote placed the cellar system among Hungary's seven most interesting architectural monuments. The roughly 90-minute tour is split in two: the first half covers cellar construction, grape growing and winemaking, the second introduces period trades and professions as a kind of time travel.
