63 Square (the 63 Building) is a 249.6-meter gold-clad skyscraper on Yeouido island overlooking the Han River, one of Seoul's most iconic landmarks since it opened in 1985. After the former Aqua Planet 63 aquarium and '63 Art' observatory closed in June 2024, the tower underwent a major cultural makeover. In June 2026 it reopened with Centre Pompidou Hanwha (the Asian branch of France's Centre Pompidou) and a new rooftop observatory called '63 SkyPicnic', reborn as a mixed cultural complex of art museum, river-view deck, and fine dining.
Centre Pompidou Hanwha: The Asian branch of France's Centre Pompidou, opened June 4, 2026. Its inaugural show 'The Cubists: Inventing Modern Vision' gathers 112 works by 54 artists including Picasso and Braque (June 4-Oct 4, 2026)
63 SkyPicnic: A rooftop observatory reopened after 16 years, pairing a 60th-floor indoor viewing deck and media art with a 63rd-floor outdoor rooftop garden for panoramic Han River views from about 250 m up
Golden facade: Famous for its 14,000 glass panels coated in 24-karat gold that shimmer in sunlight, making it a prized spot for sunset and night views
63 Buffet Pavilion: Relaunched July 1, 2026 as a high-end reservation-only dining venue, serving touches like a welcome lobster tail
Han River setting: Adjacent to Yeouido Han River Park, easy to combine with riverside walks, cycling, or a cruise as part of a west-Seoul itinerary
