The Kursaal Bridge, is a beautiful and futuristic bridge that connects the Central Boulevard of Donostia with the Zurriola street in the Gros district of San Sebastian. The bridge was built in 1915, but due to the continuous battering of the waves, its structure had to be modified just three years later. The bridge is supported by three central supports and two wall-breasts, and it spans four spans of the river. The futuristic and expressionist streetlights on the bridge add to its glamour and beauty, illuminating the Kursaal Palace, which has two turrets designed by Rafael Moneo that resemble stranded rocks, and the Victoria Eugenia Theatre, which has hosted important cultural events throughout San Sebastian's history. The Kursaal Bridge is the first of four bridges located in the estuary of the River Urumea, and it offers an incredibly beautiful promenade with stunning views of the surrounding areas. Despite its age, the bridge remains a popular attraction for tourists and locals alike, who enjoy strolling along its walkways and admiring its unique design and architecture.
