Oukashi Art Museum is a small gallery in Acre's old city devoted to Avshalom Okashi, an Israeli painter who lived and worked in Acre for much of his life. It sits close to the Hammam al-Basha and the Hospitallers' Fortress, so it is easy to add to an old-city walk.
The visit is short, but useful if you want a quieter stop between Acre's larger Crusader and Ottoman sights.
