Basel Cathedral was built between 1019 and 1500 in Romanesque and Gothic style. The cathedral obtains its recognizable red colour thanks to the red sandstone used for its construction. The old Catholic church became Protestant during the 16th century.
The synagogue in Basel, also known as the Great Synagogue, was built between 1866 and 1869. The synagogue was first enlarged in 1892 with the addition of a second dome, and the building was restored after the Second World War in 1947.
Edification started in 1213. It experiences several successive fires during its construction. It was completed around 1450, when the French took back the city from the English.
