Kaunas Castle

Start with the bricks. Put a hand against the round tower and feel how rough they are. Each one is dark red, uneven, and a little rounded at the edges after centuries of rain. Below them, the base of the wall is built from large grey field stones set in mortar. Somewhere behind you, the two great rivers of Lithuania meet. On a still morning you can hear birds over the water and the low hum of the old town waking up.

This is Kaunas Castle. What stands here today is only a fragment. There is one tall round tower, part of a second tower, and a section of the old defensive wall. Much of the rest is gone. Still, this small cluster of brick and stone is one of the oldest castles in Lithuania. It holds the starting point of the whole city around you.

Look at the location first, because it explains everything. The castle sits on low ground near the point where the Neris River flows into the Nemunas. Rivers were the highways of medieval Europe. Whoever controlled this junction controlled boats, trade, and the routes of armies. A fortress here could watch traffic on both rivers at once. That made the site valuable... and it made it a target.

The castle you see belongs to the Gothic period. In this part of Europe, Gothic builders worked mainly in brick, because good building stone was scarce. So the castle uses stone only where strength mattered most, in the foundations, and brick everywhere above. Historians generally place the first masonry castle here in the fourteenth century. There may well have been an earlier wooden fort on this spot, as there was at many Lithuanian strongholds.

The great enemy of that age was the Teutonic Order — a German crusading order of knights. By the fourteenth century, Lithuania was the last pagan state in Europe. The Order used that as a reason for decades of raids and campaigns along the Nemunas. Kaunas stood directly in their path. This castle was part of a chain of river fortresses meant to stop them before they reached the heart of the country.

In 1362, the Teutonic Knights besieged Kaunas Castle. Chronicles describe a long and heavy siege, with siege towers and machines brought up the river. The defenders held out for weeks. In the end the castle fell and was destroyed. It is one of the best-known episodes in Lithuanian medieval history. For many Lithuanians, the defence of Kaunas is a symbol of stubborn resistance against a stronger enemy.

Here is the first thing many visitors miss. The castle did not stay in ruins. The Lithuanians rebuilt it, and they built it stronger. The walls became thicker, and the towers were improved for a changing style of warfare. Gunpowder was arriving in Europe. Later towers in castles like this one were adapted for early firearms, with openings for guns rather than only for archers.

Then history changed direction. In 1410, the combined forces of Poland and Lithuania defeated the Teutonic Order at the Battle of Grunwald, one of the largest battles of medieval Europe. After that, the threat along the Nemunas faded. A frontier fortress was no longer so important. Over the following centuries, the castle lost its military role. At different times it served as a residence for officials, and later it was used as a prison.

Now the second surprise. The greatest enemy of this castle was not an army. It was the river. Over the centuries, the Neris slowly ate into the bank. Floods and erosion carried away parts of the walls and towers. That is one main reason why so little of the castle survives. When you look at the empty ground around the tower, you are partly looking at the work of water, not war.

There is also an older story about this place, and it belongs to legend, not to history. According to an old tale, a Roman nobleman named Palemon came to these lands with his followers. One of his sons, Kunas, is said to have founded a settlement here, and the city took his name. Historians do not treat this as fact. But the story shows how people once wanted to link Lithuania with ancient Rome.

The castle you see today is partly restored. Work in the twentieth century and again more recently stabilised the ruins and rebuilt some sections. If you look closely, you can often tell old brick from new. The older bricks tend to be darker and more irregular. The newer ones are cleaner and more even. Today the castle is used as a museum space and a venue for exhibitions and events.

Near the castle, you may notice a modern sculpture of a mounted knight with a raised sword. This is the Vytis, the charging rider from the Lithuanian coat of arms. The figure appears on the national flag of state, on coins, and on official seals. Seeing it beside these medieval walls makes a quiet point. The knight on the shield and the castle on the river come from the same long story.

From here, the old town of Kaunas opens out to the east. A short walk takes you to Town Hall Square, with its tall white town hall, and to the brick Gothic churches nearby. Behind the castle, the green park at the meeting of the rivers is a good place to sit. Locals walk dogs, cycle, and fish along the banks. It feels calm now, far from sieges and siege towers.

Before you leave, stand back and look at the tower one more time. Notice how the light falls on the red brick, and how the grey stones at the base hold it up. Then turn toward the water, where the two rivers meet. That meeting point is the reason this castle exists — and the reason Kaunas exists. As you walk away into the old town, you are walking along the same ground the city first grew from.
