The history of Wiesbaden is rooted in deep antiquity, when its healing hot springs attracted the attention of the Romans. It was they who founded a settlement here called Aquae Mattiacorum, meaning "Waters of the Mattiaci," in honour of the local Germanic tribe. The Romans built a military post and thermal baths here, and a fragment of their defensive wall, known as the Heathen Wall (Heidenmauer), can still be seen in the city centre as a reminder of its ancient past. The first written mention of these springs belongs to the pen of Pliny the Elder and dates back to 77 AD.
The modern name of the city was first recorded between 828 and 830. Charlemagne's biographer, Einhard, mentioned this place as "Wisibada" — "baths in the meadows." For centuries, the 26 hot mineral springs remained Wiesbaden's main treasure and economic engine, invariably attracting travellers seeking healing and rest.
The true flourishing of the city began in the 19th century when, in 1815, Wiesbaden received the status of the capital of the Duchy of Nassau. This event turned it into a majestic residence and launched large-scale construction. During this period, the elegant architectural appearance of the city, for which it is famous today, was formed. Iconic buildings such as the luxurious Kurhaus with its famous casino and the Ducal Palace were erected, and the city itself became a centre of social life.
Thanks to its mild climate and luxurious atmosphere, Wiesbaden soon earned the nickname "Nice of the North." The city became a favourite holiday destination for the European aristocracy, including members of the Imperial Romanov family. Famous cultural figures such as Fyodor Dostoevsky and Richard Wagner also visited here. This era cemented Wiesbaden's reputation as one of the most fashionable and aristocratic resorts in Europe, a legacy that is still felt to this day.
