The medieval town was originally surrounded by a moat with water. The triangular-shaped older core lies between two alleys, one of which has an urban street character, while the other retains more of a rural, village centre character.

The old town of Büren is listed as a national object in the Federal Inventory of Cultural Property. There are therefore numerous places of interest not to be missed. Büren an der Aare Castle is the most important castle in Bern and was built in the first half of the 17th century. It was built between 1621 and 1624 and is considered one of the most beautiful bailiff residences in the surrounding area. The Bürener Spittel, or simply ‘Spittel’, is a building with an eventful past, located at the eastern entrance to Stedtli. The ‘Spittel’ once served as a hostel for pilgrims and travellers. Today it has become a local museum housing numerous collections of local history. The wooden bridge is a landmark of Büren and has been of supraregional importance for centuries. The 108-metre-long bridge allows the crossing of the Aare and has connected the Stedtli with the district of Reiben (part of Büren since 1911) since 1275. The current wooden bridge was only opened in 1991. Its predecessor was the victim of an arson attack on 5 April 1989. In addition, the bridge in Büren an der Aare burned already in 1798, when during a hasty retreat of Napoleon’s troops, the locals set fire to it. Finally, the most impressive building of the Büren ‘Ländti’ is a former Bernese granary. Its size gives an idea of Büren’s importance as a trading and transhipment centre. The ground floor served as a cellar, while the upper floor was used to store grain. The restoration of the historic building, which has been ongoing for more than 30 years, began in 2003. The former granary now houses the restaurant ‘Il Grano’.
