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.
