Originally built of wood in 1657 near Königsberg’s fortifications, the gate was rebuilt in brick by order of Frederick II of Prussia. In 1843 it underwent a major renovation, gaining pointed pediments, cruciform sandstone flowers, stylized leaves, coats of arms and medallions. Bas-reliefs of Field Marshal Hermann von Boyen and Lt.-Gen. Ernst von Aster flank the passage. Executed in pointed-arch Gothic, its proportions lend a sense of height despite its modest size.
