Fifteen undulating agricultural miles south of Dubuque, the tiny hamlet of St. Donatus (pop. 135) is widely advertised as a historic and picturesque Luxembourg village, mainly thanks to the handsome masonry of the Gehlen House (563/773-2480 or 800/280-1177), a 150-year-old home now used as a restaurant and B&B. Other eye-catching structures are the Roman Catholic church and Pieta Chapel atop the adjacent Calvary Hill. If you wish to make a pilgrimage up the Way of the Cross to the Chapel, start behind at St. Donatus Catholic Church, east of Kalmes Restaurant. There’s a nice view from the top—the other set of spires across the valley belongs to the German Lutheran St. John’s Church.
