A Grand ESTO Welcome – Secrets of Philly: Beneath the Surface

August 23, 2026 - 5:00pm to 6:30pm

Step beyond the familiar and into the hidden layers of the Masonic Temple at One North Broad, one of Philadelphia’s most extraordinary architectural landmarks, where untold stories, whispered alliances, and unexpected discoveries await.

Join us at ESTO 2026 for an evening of intrigue, connection, and discovery in the heart of Center City Philadelphia. Engage with peers – both longtime colleagues and ESTO first-timers as you celebrate the kick-off to ESTO at this architectural icon, a National Historic Landmark known for its ornate design and rich symbolism.

At our pre-dinner reception, you’ll enjoy creative culinary offerings inspired by Philadelphia’s vibrant food scene, craft cocktails (and zero-proof sips).

You will uncover a world of intrigue—through immersive encounters, concealed spaces, and experiences that blur the line between past and present. Not everything is meant to be seen… but everything invites exploration.

Walk Time: Four-minute walk from the Philadelphia Marriott Downtown
