Uxmal, located about 80 kilometers south of Mérida in the Puuc region of Yucatán, is one of the most architecturally refined ancient Maya cities. Unlike other major Maya sites built with steep pyramids and narrow passageways, Uxmal is known for its smooth limestone structures, wide plazas, and intricate stone mosaics. One unique experience available to visitors is the nightly light and sound show, which uses colored projections to highlight carvings and narrate local legends and Maya cosmology.

Ancient history comes alive in Athens, the capital of Greece. Gaze in wonder at the Acropolis and its iconic crown, the Parthenon. Take a deeper dive into the past and visit both the Acropolis Museum and the National Archaeological Museum, which house fascinating artifacts from this ancient city.

The Iron Gates, a dramatic gorge along the Danube River, is a spectacular natural wonder straddling the border between Romania and Serbia. This striking geological formation carves its way through the Carpathian Mountains, creating breathtaking views that captivate all who visit.

A series of gates surrounds the two centers of ancient, medieval Fez (sometimes spelled Fes). The principal axes link the center to the gates and a street surrounds the heart of the old city. The Kairouan quarter, which is longer, is crossed by an artery. Narrow, tortuous pedestrian streets, covered passages, stairs and numerous dead-ends make up the dense layout with few urban squares.

Denmark is a country shaped by water, wind, and centuries of human ingenuity. In places like Roskilde, visitors can see five original Viking ships at the Viking Ship Museum and even try rowing a replica longboat across the fjord. In Copenhagen, the harbor once used by merchants and sailors now welcomes swimmers, kayakers, and ferries, with historic warehouses repurposed into restaurants and museums.
