Discover Kaunas: Castle, Old Town, and Modern Architecture

• Kaunas lies at the confluence of the Nemunas and Neris rivers; its medieval castle stands near this river landscape.
• Kaunas Castle was built in the 14th century as a defensive fortification against attacks by the Crusaders.
• “Modernist Kaunas: Architecture of Optimism, 1919–1939” was added to the UNESCO World Heritage List in 2023.
• The listed ensemble includes areas of Naujamiestis and Žaliakalnis, not just individual buildings.
• The Old Town lies within the UNESCO site's buffer zone. It is a distinct focus for visitors, but is not part of the listed core area.
• During the interwar period, Kaunas was Lithuania’s provisional capital; this era shaped the city’s modern character.
• The Kaunas School of Architecture combined modern movements with local and national design ideas.
• Churches, museums, and interiors have their own visiting hours; check the latest information before you go.

Kaunas is easy to understand through its setting: at the confluence of the Nemunas and Neris rivers, historic districts, riverbanks, and green spaces meet. Start in the heart of the Old Town and use the castle as a landmark. The fortress dates back to the 14th century and was built to defend against attacks by the Crusaders. Today, it is primarily a starting point for exploring the city’s medieval history and setting. Check current opening hours, exhibitions, and any restrictions with the operator before your visit.

Don’t treat the Old Town as merely a series of photo stops. Take time to enjoy its squares, streetscapes, and the churches that define the historic centre. Whether you can visit a church interior depends on its schedule for the day; services and local rules take precedence at religious sites. For a closer look at sacred architecture, see the guide to churches in Kaunas. The Kaunas city overview is also helpful for getting a first impression of the districts and how to get around.

The UNESCO listing is titled “Modernist Kaunas: Architecture of Optimism, 1919–1939”. Recognised in 2023, it covers an urban ensemble of architecture, streets and urban planning, and landscape. The designated areas are in Naujamiestis and Žaliakalnis. This matters when planning your route: the medieval Old Town is in the buffer zone, while the core area showcases the modern urban development of the interwar period. The two areas complement each other, but they are not the same protected site.

In the streets of Naujamiestis and Žaliakalnis, you can see how European modernism combined with local influences. The Kaunas School was not a single, uniform architectural style: architects blended modern principles with a range of historical references and the search for a distinct national form. So look at entire streets, squares, and how buildings fit into their surroundings—not just individual façades. The official introduction to modernist architecture from KaunasIN offers a concise introduction to this development.

After the First World War, Kaunas became the political and cultural centre of independent Lithuania, while Vilnius could not serve as the capital. As the provisional capital, Kaunas developed rapidly between 1919 and 1939. The architecture of this period is therefore both a record of the city’s building history and a testament to a distinctive chapter in Lithuania’s national history. To better understand the political context, pair your city walk with an overview of the Republic of Lithuania from 1918 to 1940.

The modern city did not develop in isolation. Squares, residential districts, green spaces, and the relationship with the river landscape all contribute to the character of the UNESCO ensemble. The area is easier to appreciate by exploring several streets than by trying to tick off as many individual buildings as possible in a short time. For specific walks, it’s a good idea to have a city map handy and choose which areas to visit based on your starting point.

Kaunas offers plenty of options for a rainy day or a deeper dive into history. First decide whether you’re interested in local history, art, architecture, or religious heritage, then check opening hours, exhibition information, and admission requirements directly with the venues. You’ll find an overview of collections across the country in our guide to museums in Lithuania. Also bear in mind that special exhibitions or seasonal closure days can affect your plans.

For a meal or a break, try some local dishes rather than overloading a short walking tour with extra trips. Our guide to Lithuanian cuisine can help you choose traditional foods and products. If you need an accessible itinerary, check with each venue in advance about steps, lifts, surface conditions, and toilets. General advice on accessible travel planning in Lithuania can help with preparations, but it does not replace getting specific information from the venue.

On your first day, you could set aside the morning for the Old Town and castle, then explore part of Naujamiestis later. For interwar modernism, it’s better to choose one continuous area than to rush through both designated areas. A second day gives you time for Žaliakalnis, a museum, or a longer riverside break. Adjust the order according to the weather, opening hours, and where you arrive.

If you only have a weekend, compare your route with our suggestions for 48- or 72-hour city breaks. For arrivals by air, see practical information about Kaunas Airport; check the current connection into the city for your travel date. If you’d like to include river scenery and other riverside destinations, you can also read about holidays along the Nemunas. This is an option for longer stays, not an essential part of a city walk.

• Visiting hours: The castle, museums, and churches are run by different organisations. Check on the day whether interiors are open to visitors.
• Getting around: The Old Town and modern districts are not all close to one another. Group sights by area and allow time for breaks.
• Accessibility: Ask individual venues about step-free entrances and accessible toilets. Historic paving and occasional steps can make getting around more difficult.
• Weather: A museum can be a good alternative on a rainy day; only set aside time for one if it’s open that day.
• Be considerate: Churches, homes, and courtyards are more than just attractions. Respect signs, quiet areas, and private entrances.

What does the Kaunas UNESCO World Heritage site include?

The listing protects the ensemble “Modernist Kaunas: Architecture of Optimism, 1919–1939” in parts of Naujamiestis and Žaliakalnis. It recognises the area’s architecture, urban planning, and landscape as a whole.

Is the Old Town part of the UNESCO core area?

No. The Old Town lies within the listed site's buffer zone. It is still an important historic part of a visit to the city and pairs well with the modernist districts.

Is one day enough for Kaunas?

One day is enough to get a first impression of the Old Town and castle, along with one selected area of interwar modernism. A second day makes it more relaxed to visit both UNESCO areas, museums, and enjoy longer breaks.

Can I explore Kaunas on foot?

Some areas are easy to explore on foot. Since the Old Town, Naujamiestis, and Žaliakalnis are separate districts, plan your walks and breaks together and consider using public transport where needed.

When should I visit the castle, churches, and museums?

Opening times vary by venue and may change seasonally or because of events. Check the latest information from the operators before planning indoor visits.

How can I plan an accessible visit?

Ask each venue about access, steps, lifts, and toilet facilities. Road surfaces and slopes can also vary between districts, so plan your route according to your needs.
