The building that houses the Charles Allis Art Museum, 1630 E. Royall Pl., on Milwaukee's East Side was designed and built as a home, but in a sense it's also always served as an art museum. Built by a captain of industry, Charles Allis, the house -- designed by Alexander Eschweiler and built in 1909 -- was planned as more than a home for Eschweiler and his wife, Sarah. It was meant to be a showplace for their ever-growing collection of art.
