The reader who nominated the Shofuso Japanese House and Garden says this one is more “off the beaten path,” but we say that’s a good thing. The traditional-style Japanese house was designed by midcentury modern architect Junzo Yoshimura in 1953 and built in Japan. Today, the hidden gem welcomes thousands of visitors during the Cherry Blossom Festival and hosts plenty of events, like tea time, in the Shofuso Japanese House.

Traveling through 30th Street Station isn’t always an enjoyable experience, so thank goodness for its Art Deco interiors that always make people stop and stare. 30th Street Station is considered one of the last remaining grand stations in the country and is listed on the National Register of Historic Places. Also, you might want to get a good look at it now—the 30th Street Station District Master Plan has some big changes in store to improve the station, both inside and out.

When news broke that the world-class Barnes Foundation would be moving from its original location to a new museum in Philadelphia, the response was mixed. Could architects Tod Williams and Billie Tsien ever replicate the awe-inspiring and world-class art gallery of Dr. Albert C. Barnes in a new build? Indeed, today the Barnes Foundation on the Benjamin Franklin Parkway is considered one of the best examples of new architecture in Philly, and its interiors play a big role in that. In addition to the 12,000-square-feet of gallery space, the museum features a wealth of public spaces, both inside and out.

Of the two churches on this list, St. Rita’s Catholic Church is considered a National Shrine. The church, which has served South Philly since the early 1900s, was designed by architect George Lovatt and its colorful and stately interiors continue to wow to this day.

As the largest city building in the U.S., Philadelphia’s City Hall is an incredible work of architecture that boasts more than 700 rooms. The atrium, with its winding staircase is impressive alone, but there are plenty of other rooms worth exploring, too, including the Mayor’s Reception Room that’s decked out with fanciful crown molding and chandeliers.

The Masonic Temple on North Broad Street right next to City Hall boasts one of the most jaw-dropping interiors in the city. The building was designed by noted architect John T. Windrim in 1873, but artist George Herzog is responsible for decorating the interiors, which took almost two decades to complete.

The historic PSFS building, now the Loews Philadelphia Hotel, is often touted for being one of the first International-style skyscrapers in the nation. But its Mad Men-esque interiors are just as notable. Fun fact: The clocks in the lobby and above the elevators were designed by Cartier.

Some incredible Art Deco interiors hide behind the walls of the former US Post Office at 9th and Market, also known as the William Penn annex. The post office first opened in 1937 and was designed by Harry Sternfeld of the Ballinger Company. As one Curbed reader put it, “Every time I’m in there I imagine the 40-plus Art Deco windows all open and in use way back when.”

The Curtis, originally the home of the Curtis Publishing Company Building, recently finished up a $25 million renovation, bringing new retail, office space, and apartments to the mix. But its interiors have been wowing folks long before renovations started. The incredible atrium is definitely a showstopper, as is the Dream Garden, a mosaic featuring 100,000 pieces of favrile glass. Plus, there’s a bonus to the stunning space: You can do yoga at The Curtis in the summer. The free session has finished up this year, but be on the look out for next summer’s offerings.
