The fortress was originally named Dünamünde when it served as a Swedish stronghold.
It is built in a classic pentagonal 'star fort' design with five bastions.
During the late 19th century, the Russian Empire significantly modernized the fortress, adding brick barracks that still stand today.
The fortress occupies a position on the Daugava River's left bank, historically the primary maritime gateway to Riga.
Large portions of the original 17th-century ramparts remain largely intact, shielded by thick layers of earth.
The site was used as a restricted military zone during the Soviet occupation of Latvia, keeping it inaccessible to the public for decades.
It is one of the few remaining examples of Swedish-era fortifications in the Baltics that hasn't been completely urbanized.
Daugavgriva Fortress is a 17th-century star-shaped fortification located at the mouth of the Daugava River in Riga, Latvia. Originally constructed by the Swedish Empire in 1641, it served as a critical defensive point controlling entry into the city's harbor. The site features extensive earthen ramparts, moats, and remnants of military architecture spanning Swedish, Russian, and Latvian periods. It played a major role during the Great Northern War and remained a functional military object until the late 20th century. The fortress complex is currently undergoing gradual restoration efforts led by volunteer organizations and local authorities. It stands as a rare example of a bastion-style defense system in the Baltic region. The site's strategic geography allows for views of the Baltic Sea and the confluence of the river. Archaeological layers at the site reveal centuries of shifting control over the Daugava estuary.

Wear sturdy, closed-toe walking shoes as the grounds are uneven, grassy, and contain loose gravel.
Bring mosquito repellent if visiting during summer months, as the marshy river delta environment attracts insects.
Bring a flashlight if you plan to explore any of the partially accessible cellar or brick tunnel structures.
Do not attempt to climb or enter marked-off decaying structures, as they are not structurally secured for tourists.
The site is primarily open for guided tours and public access during the summer season; winter access is often limited due to snow and icy conditions.
Stay on marked paths; the historical structures are fragile and some areas are unstable.
