The oldest castle in the Czech Republic: Přimda, Prague Castle or Loket?

Czech heritage records · the oldest castles and hillforts

“What is the oldest castle in the Czech Republic?” comes up in quizzes, school projects and trip planning. The answer depends on what we mean by a castle. A stone castle with a tower and walls, or also the earlier hillforts surrounded by ramparts and wooden palisades? A castle that still stands, or only the site where one once was?

We went through the Archaeological Atlas of the Czech Academy of Sciences, material from the National Heritage Institute, castle websites and the latest research. For each castle we say how it is dated and where sources disagree.

Hillfort or castle?

The early medieval centres of power in the 8th to 10th centuries were hillforts: large sites fortified by ramparts of timber, earth and stone, with wooden buildings inside and later stone churches. Castles developed from them. Stone castles with a residential tower and masonry walls appear in the Czech lands only in the 12th century.

So “the oldest castle in the Czech Republic” has two honest answers. Among hillforts, Mikulčice, Stará Kouřim and Prague Castle lead; among stone castles, Přimda, Cheb and now Loket.

The oldest hillforts: Mikulčice, Kouřim, Libice and Levý Hradec

The oldest fortified centres are in Moravia and Central Bohemia:

• The Slavonic hillfort at Mikulčice – a Great Moravian centre of the 8th–9th centuries. Since 1954 archaeologists have uncovered ramparts, the foundations of churches and a palace, and more than 2,500 graves.
• Stará Kouřim – a hillfort from the end of the 8th to the early 10th century. The Archaeological Atlas calls it the largest early medieval fortification in Bohemia.
• Libice nad Cidlinou – seat of the Slavník dynasty, settled from the early 9th century. The Přemyslids captured it in 995.
• Levý Hradec – a Přemyslid hillfort above the Vltava, fortified around the mid-9th century. Prince Bořivoj built the first church in Bohemia here in the 880s.
• Budeč – a hillfort from the end of the 9th century. It has the Rotunda of St Peter and St Paul from around 905, the oldest standing building in the Czech Republic.

Prague Castle: the oldest castle still in use

According to tradition, Prague Castle was founded by Prince Bořivoj, the first historically documented Přemyslid. The year most often given is around 880, though interpretations range from 870 to 885. According to the Archaeological Atlas, the site was fortified by the mid-9th century. The first church inside was the Church of the Virgin Mary from the late 9th century; the oldest one still standing is St George's Basilica, founded around 920.

Prague Castle became a stone castle only in the 12th century. The Archaeological Atlas dates the first all-stone wall to the early 12th century; other sources link a major Romanesque rebuilding with Prince Soběslav I from 1135. Remains of the Romanesque palace and wall survive beneath the Old Royal Palace.

What no one can take from Prague Castle is its exceptional continuity as a seat of government for more than a thousand years. Princes and kings lived here from the 9th century, presidents since 1918. Archaeological finds are shown in the exhibition “The Story of Prague Castle” in the Old Royal Palace.

Přimda: the oldest stone castle in the Czech Republic

The ruins of Přimda stand on a hill above the small town of the same name near Tachov, close to the Bavarian border. The National Heritage Institute, which manages the castle, calls it the oldest surviving stone castle in the Czech Republic. It was built by the 1120s at the latest.

The often-quoted year 1121 is uncertain, however. For that year the chronicler Cosmas mentions a castle “built by Germans”, but does not name it. That it was Přimda is only an assumption. The first reliable mention dates from 1126, when Prince Soběslav I had the castle repaired.

What survives is the Romanesque residential tower, the so-called donjon, with remains of a fireplace and a garderobe, the oldest surviving castle toilet in the Czech Republic. The room next to it served as a prison, and served well: Prince Soběslav II was held here twice, about fifteen years in total, and in 1249 Přemysl, later King Ottokar II, was imprisoned here.

What you can see today: freely accessible ruins with the Romanesque tower, a twin window, the fireplace and the garderobe. More information is on the castle website (hrad-primda.cz).

Loket: a hundred years older than thought

Loket Castle above the Ohře river is first mentioned in writing in 1227. In March 2026, however, the National Heritage Institute published research showing that the castle was built at the turn of the 11th and 12th centuries, and straight away as a fully stone castle built with mortar. The key was radiocarbon dating of food fat residues in pottery found on site, used on medieval material in the Czech Republic for the first time. The research was led by the archaeologist Filip Prekop.

Does that make Loket as old as Přimda, or even older? No source puts it that way yet. Unlike Přimda, though, Loket still stands complete, albeit in its later Gothic form. You can see a Romanesque rotunda from the late 12th century and a 26-metre tower.

Cheb: older, but not in Bohemia at the time

Cheb Castle is a nice trick question for quizzes. Margrave Diepold II of Vohburg built a stone castle here in the first half of the 12th century; the castle website gives around 1125. Around 1180 Emperor Frederick Barbarossa rebuilt it as an imperial palace (Pfalz). It is the only Staufer palace in the Czech Republic, and the Black Tower, a unique two-storey chapel and the ruined palace survive.

In the 12th century, however, the Cheb region did not belong to the Czech state. It became a permanent part of the Kingdom of Bohemia only in 1322. That is why Cheb is usually not counted among “the oldest Czech castles”. The castle was also the scene of a Czech “red wedding” in 1634, which we cover in our article Czech Game of Thrones.

And the oldest castle in Moravia?

No reliable source awards the title “oldest castle in Moravia”. The candidates by written records are:

• Bítov above the Vranov reservoir was built in the 11th century on the site of an earlier hillfort. The castle website gives a first mention in 1046, Wikipedia 1061.
• Olomouc Castle grew out of a Great Moravian hillfort and is mentioned by Cosmas in 1055. The Zdík Palace from the first half of the 12th century survives.
• Brno Castle, mentioned in 1091, has disappeared.

Castles that look older than they are

According to legend, Vyšehrad was the seat of Krok and Libuše and therefore older than Prague Castle. Archaeology says the opposite: the hillfort was founded only in the mid- or late 10th century, about a hundred years later.

Zvíkov, with its Hlízová tower of rough-faced stones, looks ancient. It is first mentioned only in 1234, a hundred years after Přimda.

Křivoklát is mentioned by Cosmas as early as 1109 or 1110, but at that time it was a princely hunting lodge. The stone castle as we know it dates from the 13th century.

Trip ideas

West Bohemia: Přimda, Cheb and Loket lie not far from each other in the west of Bohemia and make a good weekend trip. You can see the three oldest stone castles in the country in one go.

Around Prague: Levý Hradec, Budeč and Prague Castle show how the Přemyslid state began: from a hillfort with the first church to a seat of power that still works today.

We do not list opening hours or admission prices because they change. You will find them on the websites of the castles and their managers, above all the National Heritage Institute and the Prague Castle Administration.
