Gdynia: Poland’s Modernist Seaside City Now a UNESCO World Heritage Site

July 28, 2026

From a small fishing village to a symbol of European modernist architecture: this is how the present day rewrites the history of Gdynia, on the Baltic Sea coast, a urban transformation achieved in a few decades. In 2026 the city’s modernist center officially entered the UNESCO World Heritage List, earning a recognition that rewards its buildings, but above all an innovative vision of a city born in the 1920s and 1930s.

Unlike many UNESCO sites tied to ancient ruins, castles or medieval centers, Gdynia tells a contemporary story, that of a city designed from scratch to become the great port of independent Poland, a place where architecture, the sea and quality of life were meant to coexist in balance.

The new UNESCO site encompasses the historic heart of the city, an area of about 87.9 hectares where today you can still admire buildings with modern lines, broad avenues and districts designed according to the principles of European modernism. A recognition that also invites travelers to discover a Poland different from the best-known routes: a destination facing the Baltic where the charm of the sea meets one of the most interesting urban planning experiences of the twentieth century.

Why Gdynia Became a UNESCO World Heritage Site

The peculiarity of Gdynia stems from its extraordinary history. At the beginning of the twentieth century it was only a small coastal village, but after the birth of the Second Polish Republic it was chosen as the site of the new great national port.

Between the 1920s and 1930s the city completely changed its look: architects and urban planners were called to create a modern, functional center, open to the future, capable of representing the identity of an independent Poland. What emerged was a unique example of modernist urban planning. The buildings were designed to offer greater natural light, healthier spaces and a better relationship between housing, greenery and the maritime environment.

It is precisely this harmony between architecture and landscape that convinced UNESCO. The recognition also rewards the local community’s ability to preserve this heritage over time, after more than twenty years of studies, restorations and conservation efforts.

What to See in Gdynia

Visiting Gdynia means immersing oneself in a city where modernism is not confined to museums, but remains part of daily life. The UNESCO historic center allows one to discover buildings with geometric shapes, wide boulevards and architectures that tell of the optimism and faith in progress typical of the interwar years.

Among the most fascinating elements there is the ongoing relationship with the sea: the port, the promenade and public spaces were conceived as integrated parts of the city, creating an urban environment where residents and visitors could live in close contact with the Baltic. In addition to the architecture, Gdynia counts museums, scenic walks and a relaxed seaside atmosphere typical of a coastal town. It is one of the main stops of the so-called Polish Tri-City, together with the nearby Gdańsk and Sopot, in a route that unites history, culture and sea.
