Masonic Temple, Library & Museum
An ornate Norman-cathedral-style interior hiding in plain sight across from City Hall — most passersby have no idea what's inside.
Across the street from Philadelphia's City Hall stands an imposing stone building that looks, from the outside, like any other grand civic structure. Step inside on a guided tour, though, and you'll find one of the country's most extraordinary interiors: seven meticulously decorated lodge halls, each in a different historical architectural style, from Egyptian to Gothic to Renaissance.
Built as the headquarters of Pennsylvania's Freemasons over 150 years ago, the building still functions as a working Masonic lodge today, alongside its public library and museum of Masonic artifacts.
One-hour guided tours run several times a day, Wednesday through Saturday, led by docents who explain both the building's architecture and the history and symbolism of Freemasonry itself.
Why it's a secret
From Broad Street, it just looks like another handsome older building near City Hall — nothing on the exterior hints at the scale or ornamentation of what's inside.
How to get there
