Designed by architects Eugène Beaudouin, Urbain Cassan, and Louis de Hoÿm de Marien, the 59-story Montparnasse Tower irrevocably altered the Paris cityscape. Following its construction, the city levied a ban on new buildings exceeding seven stories; while that stricture has been relaxed somewhat in recent years, the tower still stands out from the rest of the city.
Its looks may not inspire rapturous praise, but its views certainly do. The building’s observation deck includes both indoor and outdoor viewing areas. From its heights, most of the City of Light can be glimpsed, from the Eiffel Tower to Sacré Coeur and beyond. Various ticket packages cater to individual visitors and groups; you can also explore Montparnasse Tower on a private Paris tour or glimpsed it in passing on a hop-on hop-off bus tour.
