Ajka (German: Eickau) is a town in Veszprém County, in the Ajka District. The city is located along the main road 8, 30 km west of Veszprém, 40 km north of Lake Balaton, in the Transdanubian Central Mountains, along the fault line dividing Bakony to the north and south, in a half-basin open to the west. In the north Magyarpolány, in the south Öcs and Halimba, in the west Kolontár and Devecser, while in the east Kislőd and Úrkút are the neighboring settlements. Several small streams flow through the area: the Torna and Csinger streams in the inner area, the Széles-víz, and the Csigere and Polányi streams on the border of the settlement. There is also an artificially created boating lake in the town.
Prehistory
Stone Age finds have also been found
around the settlement, proving the presence of Stone Age man. I. e.
Around 1,000 Celts settled in this area and occupied the Illyrian
castles. Flóris Rómer, a prominent researcher at Bakony, also found
the remains of such an earthen castle in Töröktető, which was named
Cservár.
The Celts were later replaced by the Romans. From
the second century a tombstone was unearthed, which Publius Sextus
Acurius Dexter and his wife Julia Prisca had erected for themselves
while still alive. Even Romans lived here when the Huns appeared in
the countryside. They were followed by the Eastern Goths, the
Longobards, and then in the 6th century by the Avars.
Later,
the area became Frankish and then Slavic, found here by the
conquering Hungarians, who occupied Transdanubia in the 10th century
under the leadership of Prince Árpád and settled.
Middle Ages
The villages, from which the town of Ajka was later merged, were
found in both 11–13. It was founded around the 16th century. Ajka,
Berénd, Bódé and Padrag were named, and Csékút, Gyepes, Rendek and
Tósok were names of geographical origin. Ajka is named after a
former landowner genus derived from the German name Heiko. Heiko was
a German knight who came to Hungary with Gizella. The first
surviving written mention of the place (Eyka) dates from 1214, but
the settlement itself is much earlier. It is mentioned as Ayka in
1278, by which time it already had a temple.
Mining and
industrialization
In the following centuries, Ajka developed
slowly. The real development came in the 19th century, after the
discovery of coal reserves in the nearby Csinger Valley in 1836. The
supplies were found by a shepherd who set fire to the area and the
fire did not want to go out. The research was started by Gyula
Puzdor, the owner of the area. Extraction began in 1869. Bernát
Neumann founded a glass factory in 1878 based on coal and railways.
The Catholic church was built in 1933-34 in the heart of the
city.
In 1937, based on the patent of Imre Bródy, the world's
first krypton factory was built in Ajka-Csingervölgy, the building
of which can still be seen today.
Later, large quantities of
bauxite were found, and an alumina factory and aluminum smelter were
built in the city. The power plant was established in 1941-42 to
serve these.
In 1950, Bóde (Wuding in German) was annexed to
Ajka, and on November 1, 1959, Ajka was declared a town and the
municipality of Tósokberénd (German: Duschigwehrend) was added,
including the Tósok, which was merged in 1950. On January 1, 1960,
its population was already around 15,000. At that time, several
factories were built in the city, and it became clear that the
settlement would become an industrial city. By 1972, there were
already 32 plants operating in Ajka.
In the 70s, the
development of the city center began. The House of Culture, the
Zenit and Horizont Department Stores, the Town Hall and the Hotel
Ajka were built, which are still the defining buildings of the city
center.
In 1971, Ajka became the district seat, and from
Devecser, in addition to the district office, the court and the
prosecutor's office also moved here. The new police headquarters was
built in 1981. In 1977, Ajkarendek (German: Eickaureindel) and
Bakonygyepest (German: Jepsching), and then in 1984 the Padragkutat,
established in 1961 by merging Csékút and Padrag, were also attached
to the city. In 1987, Ajka won the Hild Medal for "three decades of
activity in creating a city with a human face."
After the
regime change
The regime change has shattered the city’s
industry, but municipalities are working to facilitate the
establishment of new plants and restructuring. In the 1990s, the New
Atlantis Regional Alliance was formed with the goal of reviving Ajka
and its environs and initiating development. As a result, new
investors are appearing in the city’s industrial park. In 2005, the
implementation of the Agora Plan, which provided for the renovation
and reconstruction of the city center, began. Since then, the city
has been noticeably developing and organizing.
The 2008
financial crisis did not spare Ajka either, but it soon recovered
from it and there was a year when it reached 1% of the country’s
GDP. By the end of the 2010s, the city was already struggling with
severe labor shortages.
In 2010, a major industrial disaster,
the so-called a red mud disaster on the lips hit the city and its
area. However, its development has not stopped, and in the 21st
century there have been several major, spectacular investments in
Ajka, including the renovation of a city swimming pool and the
construction of an ice rink that even larger cities can envy.
During the Covid-19 coronavirus epidemic in 2020, the Magyar
Imre Hospital in Ajka also operated as an epidemic hospital.
Location and Basic Parameters
Geographic coordinates: 47°06′02″N
17°33′08″E (approximately 47.1006°N, 17.5522°E).
Municipal area:
95.05 km² (36.70 sq mi).
Elevation profile (within the city and
immediate surroundings): The town core lies at roughly 225–290 m above
sea level, while the broader municipal terrain spans a minimum of about
174 m (571 ft) in valley floors to a maximum of around 600 m (1,969 ft)
on surrounding hills. The average elevation is approximately 290 m (951
ft).
The city has developed from merged historic villages, so it
spreads across undulating hilly terrain rather than a single flat plain.
Topography and Terrain
The Bakony is a fragmented, step-faulted
mountain range of flat-topped or gently undulating plateaus and ridges,
rising generally 210–700 m across the wider region. Near Ajka, the
landscape consists of rolling hills interspersed with shallow valleys
and basins. Limestone and dolomite dominate the bedrock, producing
classic karst features such as springs, caves, and occasional sinkholes.
Some western and southern parts of the Bakony (including areas near
Ajka) also feature basalt sheets.
Key local landforms include several
valleys that dissect the hills:
The Csinger Valley
(Csingervölgy), about 4 km southeast of the city center (now
incorporated into Ajka), is an elongated NE–SW valley roughly 8 km long.
Broader rolling hills and plateaus surround the urban area, with nearby
peaks such as Kab-hegy (Kab Hill, 599 m) in the Southern Bakony visible
or accessible.
The terrain supports light hiking and offers
scenic views of forested slopes and agricultural clearings in the lower
basins.
Geology
Ajka lies in a geologically complex area
shaped by Mesozoic and Cenozoic processes. The foundation consists
primarily of Triassic, Jurassic, and Lower Cretaceous limestones and
dolomites. Overlying these in the local subbasins is the Ajka Coal
Formation (Upper Cretaceous/Santonian age), a sequence of coal seams (up
to 100+ m thick in places), marls, sands, sandstones, and carbonaceous
pelitic rocks deposited in ancient swampy and lacustrine environments.
The Csinger Valley hosts the most significant outcrops of this
coal-bearing formation, historically exploited through extensive lignite
(brown coal) mining. The region also contains economically important
bauxite and manganese deposits, which drove 20th-century industrial
development (including an alumina plant). Karstification of the
carbonate bedrock has created aquifers and paleontological sites rich in
fossils within the coal beds. Nearby features include the Úrkút karst
area (manganese-related) and broader Bakony karst plateaus.
Hydrology
As part of a karst-dominated region, Ajka benefits from
moderate precipitation that largely infiltrates limestone bedrock,
emerging as springs along the mountain perimeters. Surface drainage is
modest and consists of small streams and creeks rather than major
rivers:
The Torna Creek (Torna-patak) and its tributaries
(including streams associated with the Csinger Valley such as Csigere
and Széles) form the primary local watercourses. These belong to the
broader paleo-Torna drainage system, which ultimately feeds into the
Marcal River and then the Danube.
Valleys channel seasonal flows, and
karst aquifers supply groundwater.
No large natural lakes exist
within the municipal boundaries, but the hilly topography creates
localized wetlands and ponds in former mining or valley areas.
Climate
Ajka has a temperate climate with oceanic influences (Köppen
classification Cfb) but pronounced continental characteristics due to
its inland, mid-latitude position in the hills.
Temperature:
Yearly range typically 26°F to 79°F (−3°C to 26°C). Summers
(May–September) are warm, with July averages of highs ~25–28°C (77–82°F)
and lows ~15–16°C. Winters (November–March) are cold and often
snowy/windy, with January daytime highs around 0–3°C and nighttime lows
−2 to −3°C. Extremes rarely drop below −11°C or exceed 31°C.
Precipitation: Annual totals around 700–800 mm (higher on elevated
Bakony ridges), fairly evenly distributed but with slightly wetter
summers. Snow cover is common in winter (20–50 days depending on
elevation).
Other factors: Partly cloudy year-round; winds are
noticeable in winter. The hilly terrain and proximity to Lake Balaton
create minor microclimatic variations—cooler and more humid at higher
elevations, with some moderating lake influence from the south.
Vegetation and Natural Environment
The Bakony was once densely
forested; today, significant woodland remains around Ajka, consisting of
mixed deciduous stands of beech, hornbeam, maple, ash, and elm. Higher
elevations (500+ m) develop more “alpinelike” communities. Lower valleys
and basins have been cleared for agriculture (fields, meadows,
orchards), creating a mosaic of forest, farmland, and urban/industrial
land.
Biodiversity is high due to the karst habitats, forests, and
transitional zones. The broader Bakony–Balaton region is part of UNESCO
Global Geopark initiatives, highlighting its geological heritage (caves,
fossils, karst springs). Hiking trails wind through the surrounding
hills, offering access to scenic viewpoints, forests, and valleys.
