The imposing DANK Haus building was originally home to the Three Links Association, a fraternal order. In 1967, DANK (the Deutsch Amerikanischer National Kongress) purchased it to house their museum, art gallery, library and language school. Today, it offers more than 150 public cultural programs each year across 77,000 square feet of space. It is known by many Chicagoans for its large fifth-floor ballroom and outdoor terrace, but it contains many other hidden spaces and artifacts of interest.
