Surakarta

Widely known as Solo, this large Central Javanese city carries deep royal heritage as one of two successor states to the Mataram Islamic Kingdom, established after the 1755 Treaty of Giyanti, when Surakarta became the seat of the Susuhunan Pakubuwana. The Bengawan Solo river — celebrated in a famous keroncong song — runs along the city's eastern edge. Surakarta is also the birthplace of former President Joko Widodo and current Vice President Gibran Rakabuming Raka, both of whom served as the city's mayor.
