Indianapolis is home to great museums too, such as the Eiteljorg Museum of American Indians and Western Art, the world's largest Children's Museum, and the Indianapolis Museum of Art. The American Institute of Architects ranks Columbus as the sixth best city in the US for innovation and design, with more than 50 public buildings designed by world-famous architects. The winding hills of southern Indiana lead to historic towns such as Madison and Vevay, and in Orange County there are two stunning historic hotels, the French Lick Springs and West Baden Springs. Thrill-seekers should check out the highly-acclaimed rollercoasters at Holiday World and Splashin’ Safari in Santa Claus.
