Although Jerusalem is known primarily for its religious significance, the city is also home to many artistic and cultural venues. The Israel Museum attracts nearly one million visitors a year, approximately one-third of them tourists. The museum complex comprises several buildings featuring special exhibits and extensive collections of Judaica, archaeological findings, and Israeli and European art. The Dead Sea scrolls, discovered in the mid-20th century in the Qumran Caves near the Dead Sea, are housed in the Museum's Shrine of the Book. The Youth Wing, which mounts changing exhibits and runs an extensive art education program, is visited by 100,000 children a year. The museum has a large outdoor sculpture garden and a scale-model of the Second Temple. The Ticho House in downtown Jerusalem houses the paintings of Anna Ticho and the Judaica collections of her husband, an ophthalmologist who opened Jerusalem's first eye clinic in this building in 1912.
