Galeries Lafayette Haussmann is a landmark Paris department store known for its Belle Époque glass dome, which floods the shopping floors below with natural light. It’s open Monday-Saturday 10 AM-8:30 PM and Sunday 11 AM-8 PM, with hours shifting around holidays.
The 8th-floor rooftop terrace is free to visit during store hours, with no ticket or reservation required, and offers panoramic views of the Eiffel Tower, Sacré-Cœur, and Opéra Garnier. To reach it, take the main elevator to the 7th floor and follow signs to the small staircase leading up to the terrace.
The best time to visit the rooftop is about an hour before sunset, when the light turns golden and the Eiffel Tower begins to sparkle against the sky. The terrace can close temporarily in bad weather, so it’s worth checking conditions before making the trip up.
