This hotel was first mentioned in some documents 1418 – it’s the second oldest hotel in Switzerland.
“The history of La Couronne, or ‘the crown’, dates back more than 500 years. ‘It’s documented as the second-oldest guest house in Switzerland and is inextricably tied to the history of the ambassadorial city of Solothurn. As a social and political centre, it often played a decisive role,’ wrote the Solothurner Zeitung in a two-part series. The hotel’s history naturally includes a number of illustrious guests, such as Casanova, Napoleon, Jane Fonda and Sophia Loren.”

« When the Romans were seeking a crossing of the Aare over which to build their road from Aventicum to Vindonissa, they decided on a place which the Celts called Salodurum, or “Water Gate”. The settlement which the Romans founded here in around 20 AD also bore the name of Salodurum. In around 330 AD, this small town with temples and baths was converted into a castrum, or fortress, by the Roman military. »
