Pennsylvania offers more than just a glimpse into American history, it invites travelers to walk through it. In Philadelphia, the Liberty Bell still draws visitors from around the world, while Independence Hall, a UNESCO World Heritage Site, is where both the Declaration of Independence and the U.S. Constitution were debated and signed. Just a short walk away, modern museums like the National Constitution Center offer hands-on exhibits that connect the past to today’s civic questions.

Alberobello in southern Italy’s Puglia region captures the imagination with its distinctive trulli houses. These structures were built using a dry-stone technique passed down over centuries, without mortar or cement, and their unique form comes from layer upon layer of limestone nestled from nearby fields. Alberobello’s trulli are so remarkable that in 1996 the historic center was inscribed as a UNESCO World Heritage Site, where more than 1,600 of these buildings still stand.
