20 Must-Visit Sites on UNESCO’s Tentative List

Skip overcrowded UNESCO World Heritage Site and discover these sites on the “tentative” list instead.

During months of sitting at home dreaming of travel, our imaginations might have been drawn to famous landmarks and destinations. The 1,100-plus UNESCO World Heritage Sites are bucket-list favorites, for good reasons. But, not so many travelers known about cultural, historic, natural and built heritage sites on UNESCO’s “tentative list”. These are UNESCO World Heritage Sites “in waiting”—sites that individual states are considering for nomination onto the A-list. While some are already major attractions in their own right, others are virtually unknown to tourists.

Travelers dreaming of adding some of the world’s most impressive cultural and natural sites to their future itineraries should check out the tentative list. Visiting these places (when you can) will be an opportunity to spread tourist dollars around while still seeing some of the world’s most important heritage sites.

Located on the island of Santiago, the town developed in the late 15th century, but its current form largely took shape in the 19th century, when Praia officially became the capital. As Cabo Verde was strategically located between Europe, Africa, and the Americas, the historic center of Praia saw a lot of activity around the Trans-Atlantic slave trade. It reflects European town planning models of the 19th century, and includes a palace, a town hall, a church, barracks, and town square, and more.

Churches of the Altiplano

The altars inside are a highlight, as they’re very colorful and decorative, in contrast to the simple whitewashed or stone exteriors.

It was finally abandoned in 1840, and natural vegetation has grown up around the remains of the fortified settlement.
