Córdoba, located in the heart of Andalusia, was once the most advanced city in Western Europe. During the 10th century, it served as the capital of Al-Andalus and was a center for learning, science, and art. Today, visitors walk the same streets that philosophers, poets, and physicians once crossed. The city’s most famous landmark, the Mezquita-Catedral, reflects its layered past. The red and white horseshoe arches inside are one of the most photographed interiors in Spain.

Pagat is a historic village area on Guam's northeastern coast, known for its archaeological remains, limestone cliffs, caves, and coastal trails. The area lies within Guam's rugged northern landscape, where dense vegetation covers limestone terraces above the Pacific Ocean. Pagat is particularly significant because it preserves evidence of ancient CHamoru settlement, including stone structures, pottery fragments, and remnants of traditional village life.

Mdina is a fortified hilltop city in central Malta, known as the Silent City for its quiet streets and enclosed historic character. The former capital occupies a limestone plateau above the surrounding countryside, with massive walls, narrow lanes, small squares, and honey-colored buildings creating a compact urban landscape. The main entrance leads toward Villegaignon Street and the center of the old city, where St Paul’s Cathedral dominates Cathedral Square.

Located about twenty-five miles southwest of Rapid City, South Dakota, lies Mount Rushmore. Following Highway 244 from the west leads to the orientation center.
