The sandstone statue in the Rathaus courtyard is Lucius Munatius Plancus, a Roman senator and officer of Julius Caesar when he founded the nearby city of Augusta Raurica in 44 B.C. It is the oldest Roman colony on the Rhine. The sculpture was created in 1580 by Hans Michel from Strasbourg. In the gallery are paintings from 1610 by Hans Bock. Above the left arch is a colorful tribute to when Basel joined the Swiss Federation in 1501.
