The building was designed by military architect Gerhard Cornelius van Wallrawe, with the masonry done by Hans Jürgen Reinecke, and the façade sculptures by Bartholomé Damart.

It depicted Amphitrite, goddess of the sea in the Greek mythology, as a nude female figure, standing on a chariot drawn by two galloping horses.

[5][6] In 1942, during the Second World War, to protect the elaborate sculptures at the top of the gate, from the Alliaed bombing raids, they were taken down, and hidden in the Arkonian Woods.

[1][2] The façade of the western entrance includes a cartouche above the gate archways, featuring a monogram of king Frederick William I of Prussia, with a royal crown put on top of it, two angels to its sides, playin on trumpets, while everything is placed at the backdrop of an elaborate panoply.

The attic above the cornice of the entablature features a Latin inscription made of letters painted in gold, informing about rightful ownership of the city of Szczecin by the Margraviate of Brandenburg, after it was bought in 1719, by king Frederick William I from the Swedish Empire.

Above it, is displayed a relief, depicting the panorama of the city with Viadrus, a god of the Oder river in the local Slavic folklore, placed on the side.

[1][2][3] The inscription reads: It translates to: The façade of the eastern entrance also includes a cartouche with a monogram of king Frederick William I of Prussia, and a panoply.
