Eger, city of county status and seat of Heves megye (county), northern Hungary. It lies in the valley of the Eger River, which is a tributary of the Tisza, between the Mátra and Bükk mountains.
Eger is an old Magyar tribal city with a bishopric founded in the 11th century. The Tatar invasion of the 13th century leveled most of the town, which was one of the richest in early medieval Hungary. The remains of the fortress from which the town was defended from the Turks in 1551 are on the hill to the northeast. The Turks returned to take and occupy the town from 1596 to 1687. It served them as an important outpost, and the 115-foot- (35-metre-) high minaret is one of the town’s landmarks.
From the early 18th century Eger revived, and the number of ecclesiastical buildings that were built in the town gave rise to its name “the Hungarian Rome.” It has been an archbishop’s seat since 1804. The former Minorite Church (1758–71) is one of the finer architectural monuments of Hungary.
Beneath Eger lie 60 miles (96 km) of tunnels that in times past provided building stone, sanctuary against invading Turks, and, more recently, cellars to mature wine. The tunnels were dug in a soft rock, and subsidence has caused extensive surface damage. The national government has provided subsidies to save the town’s many historic buildings from further destruction.
The roots of Eger’s Eszterházy Károly University extend to the 18th century. Rising above the university’s Lyceum building is the Magic Tower, which houses the Center for Scientific Guidance and Methodology, a planetarium, an astronomy museum, and a camera obscura. Similarly eclectic is István Dobó Castle Museum, which includes collections related to ethnography, arts and crafts, literary history, and archaeology.
The rich soils and the favourable microclimate on the hill slopes have supported grape vines, with viticulture dating from the 13th century. Bikavér (“Bull’s Blood”), a full-bodied red wine, is Eger’s best-known wine. The city also has manufacturing industries, including print circuit boards, gas springs, and cigarettes, and a teacher-training college. Eger is the tourist centre for the Mátra Mountains, and there is a spa with numerous bathing facilities. Pop. (2011) 56,569; (2017 est.) 53,876.
