Though Johns Hopkins University anchors Charles Village, the Baltimore Museum of Art is the neighborhood's prime tourist draw—especially since admission is free. Students, professors, writers, and artists are drawn to the area's intellectual environment. Row houses along Charles, St. Paul, and Calvert streets—some of them quite large—were built in the late 1890s and early 1900s for merchants, bankers, and other professionals. These early developments were constructed on old family estates, one of which became the basis for the present-day Johns Hopkins campus. Some of the old mansions are now museums, including Johns Hopkins's Homewood House and the Evergreen House, which also belongs to the university. On the eastern and northern sides of the Johns Hopkins campus are the neighborhoods of Tuscany-Canterbury and Roland Park. Farther to the north and east are Homeland and Guilford, tony areas worth exploring for their beautiful homes and lovely, tree-lined streets.
