Tjörnin, Reykjavík

What is Tjörnin in Reykjavík?

Tjörnin is a small, prominent lake in central Reykjavík, Iceland's capital. It sits in the city centre beside Reykjavík City Hall and several museums, and most visitors to Reykjavík pass along its shore. The name Tjörnin means “the pond”.

Its position makes Tjörnin a distinctive part of central Reykjavík: a small body of water closely bordered by civic buildings, museums, and the city's streets. The pond is not separate from the urban centre; it is one of the places where Reykjavík's public life and natural surroundings meet.

What is Tjörnin's history?

Tjörnin's history reaches back to the settlement of Reykjavík. Tour material places Viking longboats along these banks, carrying the day's catch, while early settlers built turf houses beside the pond in the 9th century. The shoreline therefore belongs to a settlement shaped by nature and survival, rather than being only a modern city-centre view.

The pond also has a specific place in the history of local wildlife. In 1919, a local law prohibited hunting birds at Tjörnin, turning it into a sanctuary. That decision connects the pond's present character with its longer history: Tjörnin remains part of Reykjavík's past while continuing to support life in the modern city.

What can you see around Tjörnin?

Swans, ducks, and geese are the most visible inhabitants of Tjörnin today. They are part of the pond's present-day character, but the tour material also connects these birds with Norse diets and local lore in earlier centuries. The same animals can therefore be read through both the pond's natural present and its settlement history.

Along the shore, notice the contrast between birds on the water and the dense civic setting around them: Reykjavík City Hall, the city centre, and the nearby museums. Tjörnin's character comes from that close relationship between water, wildlife, and the institutions of Reykjavík.

Walking the shoreline gives you a compact way to consider the layers attached to this small central lake: 9th-century turf houses, Viking longboats and fishing, community, bird protection, and present-day city life. The Reykjavík: In the Footsteps of the Vikings tour is one route that visits Tjörnin and places its shoreline within the city's Viking-era story.
