L’Union Han Istanbul, Vignette Collection occupies a restored landmark on Bankalar Street in Karakoy, built between 1905 and 1911 for the French insurance company Union. The 51 rooms and suites are framed by Ottoman-influenced architecture, Art Nouveau and Art Deco detail, and a location between Galata, the Bosphorus and the historic peninsula. Banca Unione brings Turkish and Italian dining into the hotel, while the spa, gym and lobby lounges add quieter moments within the former han. The property’s identity rests on its stone facade, banking-era interiors and Karakoy street life.
