Fortunaportal, Baroque gate at Old Market Square, Potsdam, Germany

The Fortunaportal is a 27-metre-high sandstone gate on the Old Market Square in Potsdam, designed by Jean de Bodt as the entrance to the City Palace. Its dome carries a gilded copper Fortuna that turns in the wind, and the keystones of the arch show Minerva and Hercules. Eight large sculpture groups are still missing, so the gate remains a torso.

The portal was designed in 1701 by Dutch architect Jean de Bodt to mark Frederick I's coronation as the first King of Prussia. After being destroyed in World War II and demolished in 1960, it was rebuilt to its original design in 2002.

The gilded Fortuna on the dome turns with the wind and gave the gate its name; her cornucopia stands for state welfare. The keystones flanking the arch show Minerva and Hercules. Since 2002 the dome line of the Nikolaikirche, the Old Town Hall and the portal has served as a backdrop for the minister-president's New Year addresses.

The gate stands free on the Old Market Square, facing the Nikolaikirche; it is a freestanding monument and not an entrance to the Landtag building behind it. Visitors view it from the square, and the domes of the gate, the Nikolaikirche and the Old Town Hall line up along one sight axis often used as a backdrop for state broadcasts.

The Fortuna statue on top of the dome is not purely decorative but works as a real weather vane, rotating with the wind. This functional detail gives the portal its name and makes it one of the few Baroque gates where a moving element is built into the crowning figure.
