Many first-time visitors to Cleveland start at the Rock and Roll Hall of Fame and Museum. And who can blame them? The Rock Hall, as locals call it, offers boatloads of memorabilia, film clips and music -- all in a stunning I.M. Pei-designed building on the shore of Lake Erie.
But it would be a shame to visit Ohio's second-largest city (population: 444,000) and only see the Rock Hall. Cleveland has a uniquely Northeastern feel, with loads of old churches, interesting residential areas and ethnic communities.
Many attractions are 5 miles east of downtown in University Circle. You easily can walk between the botanical garden, natural history museum, art museum and performance centers. Or just stroll over to Little Italy for great bakeries and art galleries.
A $350-million expansion and renovation, completed in late 2013, has made the Cleveland Museum of Art better than ever. An airy new atrium, an increase of 33 percent in gallery space and updates throughout the museum help show off the stellar collection, which includes more than 46,000 pieces.
