Hospital Ein Kerem shares a large campus with the Hebrew University-Hadassah School of Medicine, with scientists collaborating from both institutions. The 19-story inpatient Sarah Wetsman Davidson Hospital Tower, Hadassah’s gift to the people of Israel on its centennial, dominates the Ein Kerem campus. The underground state-of-the-art surgical suites are sheltered deep in the Jerusalem hillside and fortified against conventional, biological and chemical warfare. Hospital gardens provide green space for emotional sustenance of patients and staff. The iconic Round Building, opened in 1962, is being modernized and expanded to meet the city's growing needs. Research and clinical trials draw patients from around the world.
