🇭🇺 Hungary · Lake Balaton
At the western end of the Balaton, far from the bustle of the southern beaches, Keszthely is the most elegant town on the lake. Its great draw can be seen from a distance: the Festetics Palace, one of the largest in Hungary, a lavish baroque residence surrounded by gardens that belonged to one of the country's most enlightened aristocratic families. Inside it holds the Helikon Library, the largest noble library preserved intact in Europe, with its carved shelving and tens of thousands of volumes.
But Keszthely is much more than its palace. It was the cradle of a quiet revolution: here, in 1797, count György Festetics founded the Georgikon, the first higher school of agriculture in Europe, a milestone in the history of education. It also has the Balaton Museum, which tells the natural and human history of the great lake, a historic centre with a medieval Gothic church and a beach of its own. And barely 8 kilometres away is its most famous neighbour: Hévíz, the largest bathable thermal lake in the world, where you can swim in warm water even in the depths of winter.
This guide covers the practicalities and the essentials of Keszthely and its surroundings: how to get there from Budapest, what the palace and the thermal baths cost in forints, when to go and how to plan a trip that combines culture, lake and healing waters. Unlike the rest of the Balaton, which is very seasonal, Keszthely and Hévíz beat all year round: they are the ideal destination for anyone after more than a beach.
The history of Keszthely is long and rich. Here, at nearby Fenékpuszta, the Romans built the fortress of Valcum, and after the fall of Rome the so-called 'Keszthely culture' flourished for two centuries, a community that left rich cemeteries from the fifth to the seventh centuries. The town is documented as 'Kesztel' in 1247. But the great chapter came with the Festetics family, who in the eighteenth century turned Keszthely into a focus of culture and progress: they built the great palace with its Helikon Library, and count György Festetics founded the Georgikon in 1797, the first higher school of agriculture in Europe. The family also drove the development of the spa at Hévíz, the largest bathable thermal lake in the world, whose healing waters had been known since ancient times. After the Second World War the communist regime nationalised the palace and the town turned to lake and spa tourism. The full story, with names and dates, is on our history page.

Origins, formation and what the sources say.
The history of Keszthely starts long before it existed under that name. In antiquity, the western shore of the Balaton was part of the Roman province of Pannonia, and a few kilometres from today's town, at the place now called Fenékpuszta, the Romans built a fortress of considerable size: Valcum. It was a strategic point beside the lake, at the crossing of routes running through the region, and it was in use for centuries.
The most fascinating part happened when the Roman Empire fell apart. Instead of emptying out, the Keszthely district kept a large and relatively prosperous community from the middle of the fifth century to the middle of the seventh, right in the age of the great migrations. That population left extremely rich cemeteries, with jewellery, buckles, ornaments and objects of a quality surprising for the period, which archaeologists named the 'Keszthely culture'. Its origins are debated — a surviving Romanised population, mixed with Germanic peoples and later under Avar rule — but the phenomenon is unique in the Carpathian Basin and makes Keszthely a key site for understanding the passage from antiquity to the Middle Ages.
Some of those finds are displayed today in the Balaton Museum, and they are evidence that this corner of the lake was inhabited and valued from very remote times, long before its aristocratic golden age.
In the Middle Ages, Keszthely took shape as a market town on the shore of the lake. It is documented as 'Kesztel' in 1247, and over the following centuries it grew as the commercial and religious centre of the district. A key trace of that period is the Gothic church of the Franciscans, today the church of Our Lady of Hungary, founded in the fourteenth century: it preserves valuable medieval Gothic frescoes and, in time, it would become the pantheon of the family that shaped the town's fate, the Festetics.
Like the whole country, Keszthely suffered the long torment of the Ottoman occupation. After Buda fell to the Turks (1541), the Balaton region became frontier land, shaken by raids and fighting. Keszthely was never taken and held by the Ottomans, but it lived in permanent danger: the Franciscan church and friary were fortified, turned almost into a small castle to withstand the attacks. The population shrank and life became precarious, as in so many Hungarian towns of those centuries.
When the Turks were finally driven out of Hungary at the end of the seventeenth century, Keszthely was a battered town but with a privileged position beside the lake. In the eighteenth century a noble family would buy these lands and change its history forever.
The great chapter of Keszthely was written by the Festetics family, one of the wealthiest and most enlightened aristocratic lines in Hungary, which acquired the estate in the eighteenth century. From the middle of that century they began to build the Festetics Palace, a lavish baroque residence that they extended over generations until it became one of the largest palaces in the country, surrounded by gardens and crowned by a treasure: the Helikon Library, today regarded as the largest noble library preserved intact in Europe, with its carved shelving and some 80,000 volumes.
But the Festetics family were not only builders of luxury: they were reformers. The key figure is count György Festetics (1755-1819), an aristocrat of the Enlightenment convinced that Hungary's progress ran through the modernisation of agriculture, the base of the country's economy. With that in mind, in 1797 he founded the Georgikon in Keszthely, the first higher school of agriculture in Europe. It taught crop growing, animal husbandry, forestry and estate management in a systematic, scientific way, with experimental fields and a model farm; students and experts came to Keszthely from all over the continent. It was a pioneering venture in the world history of agricultural education.
György Festetics was also a patron of letters: around 1817 he organised the 'Helikon festivities' (Helikoni ünnepségek) at his palace, literary gatherings that brought together poets and students and made Keszthely a cultural focus. Under the Festetics family, the town on the lakeshore became a small capital of Hungarian culture and progress.
A few kilometres from Keszthely, nature had left another treasure: the thermal lake of Hévíz, the largest bathable thermal lake in the world. Fed by a powerful underground spring rising from a crater some 38 metres down, the lake renews its water continuously and holds a mild temperature all year — it never drops below about 24 °C, not even in winter — which makes it possible to swim outdoors in any season. Its mineral water and the healing mud on its bottom have long been used to treat rheumatic and joint complaints.
The lake's properties were known from remote times, but its written history and its development as a spa are more recent. The scholar Mátyás Bél mentioned it in writing in 1731, and it was again the Festetics family who drove its transformation: towards the end of the eighteenth century, count György Festetics had the first wooden bathing structures built over the lake and promoted the study and use of its thermal waters. Through the nineteenth and twentieth centuries, Hévíz grew into one of the great spas of central Europe, with hotels, sanatoriums and wooden bathhouses from which you climb down into the warm water among the water lilies.
Today Hévíz is still an internationally famous health destination, and its lake — with the steam rising off the surface on cold days — is one of the most astonishing sights in Hungary. Together with the Festetics Palace, it is the reason why Keszthely and its surroundings are a destination that beats all year, and not only in summer.
The nineteenth century consolidated Keszthely as a cultured and prosperous town under the Austro-Hungarian Empire. The Georgikon evolved as an institution of agricultural education, and at the end of the century count Tasziló Festetics extended the palace with new wings in historicist style, giving it the monumental look it has today. In 1898 the Balaton Museum was founded, devoted to the natural and human history of the lake, and in 1925 it moved into the elegant neo-baroque building it occupies now.
The twentieth century brought wars and great upheavals. After the First World War and the break-up of the Empire, Hungary was left smaller and poorer. The Second World War also hit the Balaton district: in the winter of 1944-1945 the front crossed the region — the last great German offensive of the war was fought nearby in March 1945, around the lake — and the Jewish community of Keszthely, like that of so many Hungarian towns, was deported and largely murdered in the Holocaust. With the arrival of the communist regime, the Festetics Palace was nationalised in 1945 and the family stripped of its property; in time the building opened as a museum (the Helikon Kastélymúzeum), and its library and collections were saved for the public.
In the socialist decades, Keszthely and Hévíz turned to lake tourism and spa cures, receiving visitors from all over Hungary and the Eastern bloc. After 1989, with the opening up and democracy, the town restored its heritage and firmed up its profile: today Keszthely combines the aristocratic splendour of the Festetics family, the pioneering memory of the Georgikon, the great museum of the lake and the miraculous waters of Hévíz. It is the most cultured and stately face of the Balaton, a destination with history for the whole year.
