So, the Ginza line's Asakusa Station is one of the oldest metro stations from Tokyo (and from Asia) and fortunately its architecture still reflects the style of the old times: as you can see in this photo, this is one of the most beautiful metro station entrances, designed to match the architectural look of the neighboring Senso-ji Temple (same as the nearby kōban).
