In a segment of Latvijas Radio's series 'Do you know?', cultural researchers, historians, and other experts shed light on the origins of various terms, artifacts, and ideas. The historical context of Kuldiga is explored, noting that documents first mentioned the castle and the surrounding settlement as early as 1242, illustrating its long-standing presence in the region. Although only sparse evidence remains from that time, later illustrations depict the castle as a quadrilateral fortress, indicative of its architectural significance.

As the castle was constructed, small settlements gradually formed around it, leading to the development of what is now recognized as Kuldiga's old town. The castle's construction was completed by 1245, during which the area was referred to as Goldingen, meaning 'Golden City', reflecting its status in historical trade networks. Kuldiga gained city rights in 1355, marking a significant expansion of its importance, especially as it became a crucial player in the Hanseatic League, benefitting from its strategic location on trade routes.

The city's strategic positioning along the Venta river allowed for active commerce, although the river’s rapids posed navigation challenges for larger vessels. Consequently, Kuldiga emerged as a vibrant hub of trade where intensive exchanges of goods took place, illustrating its vital role in the economic landscape of medieval Latvia. Today, Kuldiga retains its historical charm, drawing interest as a cultural and historical site.
