Triangula Bastion, Riga Travel Guide

The Triangula Bastion, or Triangular Bastion, stands as a testament to Riga's rich military history. Constructed in 1727 following the Great Northern War, it was one of four bastions built to protect the city from attack. The bastion's strategic triangular shape provided a significant advantage in military architecture.In the 16th and 17th centuries, Riga developed a new bastion fort system to defend against artillery attacks. The territory of present-day Old Riga was surrounded by an earthen rampart with polygonal bastions at the corners. The Triangula Bastion, the smallest but highest of these bastions, was pentagonal in plan and open on the side facing the town. Its walls were constructed with pink and grey dolomite blocks, with an inner wall filled with sand.As firearms became more powerful, the fortifications gradually lost their importance, hindering urban development. Between 1857 and 1864, the wall was taken down, with only part of the moat preserved as the city canal.In 2000, during the construction of a new shopping mall, the remains of the bastion were discovered. Excavations revealed the most extensively investigated part of Riga's 17th–19th-century fortification system, which were preserved inside the new building. Today, the foundations of the Triangula Bastion can be seen beneath a modern office building, offering visitors a glimpse into Riga's medieval past. The site is located on 11. novembra krastmala, along the Daugava River, and is often a focal point for city celebrations.
