The Ritz-Carlton, Philadelphia

"Set within a century-old, Pantheon-inspired former bank building, the Ritz-Carlton, Philadelphia raises Center City living to classical heights. When the building opened in 1904, the Girard Trust marble dome was the largest in the country, and its columns and styling matched its inspiration down to its oculus 142 feet from the floor, the exact height as the Roman original. Today, every stay starts in this grandiose rotunda, where staff man the immaculately preserved bank-teller booths. Guest rooms and suites are in the attached 30-story office tower, gutted and transformed into a hotel by Ritz-Carlton. All 299 rooms and suites bring classic Ritz-Carlton elegance, with wood furnishings matching gold, sage, and pumpkin hues. High ceilings and picture windows with stunning city views enhance the vibe, while spa-style marble bathrooms have rain showers."
