Middle Bridge, Basel

The Basel city walls are a complex of walls surrounding the central part of the Swiss city of Basel, only partially preserved today. The first city wall was completed around 1080 under bishop Burkhard von Fenis. A newer wall was constructed around 1230, which is known as the Inner Wall. Its course was mostly identical to the Burkhard wall. In 1362 the construction of a larger wall complex began due to the city's expansion; it was completed in 1398, and is known as the Outer Wall. In 1859 the city's executives decided to raze the inner wall and gates to the ground. Three outer city gates and a short piece of the wall were saved from demolition and are being preserved as part of the city's heritage.

The Birsig is a rather small river in eastern France and northern Switzerland. Its source is in the village Biederthal, in the French Haut-Rhin department, near the Swiss border. The Birsig is about 21 kilometres (13 mi) long, and its watershed area is about 82 square kilometres (32 sq mi). It flows variably through Swiss and French territory and through the Birsig Valley. Afterwards it passes the city of Basel, where it enters the Rhine (left bank). The river Birsig originally flowed openly through Basel, but the river was long ago channelled and its banks built up to prevent water damage to the houses. The river flowed directly along the houses in the lower part of the city, where many bridges were built over. It took the fecal waste from the houses and was therefore called "the city's big cloaca", which favoured the outbreak of cholera and typhus. Nowadays the Birsig is covered over for most of its course in Basel; there are just a few hundred meters around the city zoo where the Birsig can be seen openly.

The Blue and The White House (Blaues und Weisses Haus) are two town mansions in the city of Basel. The semi-detached baroque mansions on the Rheinsprung 16 and 18 in Basel, also known as “The Reichensteinerhof” and “The Wendelstörferhof”, were built by the architect Samuel Werenfels for the brothers Lukas and Jakob Sarasin between 1763 and 1775. “The White House” belonged to Lukas (1730 – 1802) and “The Blue House” to his younger brother Jakob (1742 – 1802). The two patricians had a manufactory for silk products. Descendants of them were the founders of the Bank Sarasin & Cie. in Basel. The still mainly original interiors of the mansions were executed by highly skilled craftsmen. The stucco ceilings were made by Johann Martin Frohweis and the faience stoves were delivered by the Frisching Faience Manufactory. The numerous sopraporte were painted by German artists. The two mansions were bought by the canton and the city of Basel in 1942 and in 1968. Nowadays, they are the seat of the Department for Economy, Social Welfare and Environment.

The Basel Town Hall (German: Rathaus Basel, locally known as Roothuus) is a 500-year-old building dominating the Marktplatz in Basel, Switzerland. The Town Hall houses the meetings of the Cantonal Parliament as well as the Cantonal Government of the canton of Basel-Stadt. The Great Council Chamber at one time featured a series of frescoes painted in 1522 by Hans Holbein the Younger, which have been lost. Fragments of the work as well as some of the initial drawings are kept in the Kunstmuseum."Rathaus" literally means "council house" while the term "Roothus" in the local Basel German dialect means both "council house" but also sounds like "red house", a pun with reference to the red sandstone facade of the building.

Basel Minster (German: Basler Münster) is a religious building in the Swiss city of Basel, originally a Catholic cathedral and today a Reformed Protestant church. The original cathedral was built between 1019 and 1500 in Romanesque and Gothic styles. The late Romanesque building, destroyed by the 1356 Basel earthquake, was rebuilt by Johannes Gmünd, who was at the same time employed for building the Freiburg Münster. Ulrich von Ensingen, architect of the towers at the Ulm Minster and the Strasbourg Cathedral, extended the building from 1421. Hans von Nußdorf completed the southern tower in 1500.
