The urban areas of Kobe were devastated by the great air raids in 1945, so building No. 15 of the former settlement (the former consulate of the United States, and an important cultural property of Japan) was the only building left standing among those built in the settlement period (that is, before 1899) in the western area of the settlement, which corresponds to the vicinity of the present-day city hall of Kobe; most of the modern-era buildings that remain standing were built in the Taisho period.
神戸市街地は1945年に大空襲を受けたため、現在の神戸市役所西側一帯にあった居留地時代（1899年以前）の建物で残っているのは旧居留地十五番館（旧アメリカ合衆国領事館、国の重要文化財）が唯一で、多く残る近代ビル建築は主に大正時代のものである。
