The National Gallery of Iceland, located in Reykjavík, is a cool art museum that showcases Icelandic art and culture. Established in 1884, it started with donated artwork by Danish artists. Over the years, it became an independent institution and now features rotating exhibitions by both Icelandic and foreign artists. The gallery's building on Fríkirkjuvegur 7 houses exhibition halls, an art store, and a café, making it a great spot to explore Icelandic creativity.
