The United Nations Educational, Scientific and Cultural Organization (UNESCO) protects and preserves significant and inspirational places around the world. Locations carrying the important designation of World Heritage site provide an impressive history lesson as well as a virtual tour of many of the world’s most meaningful places. Here are five you and your family might like to visit:

1. Sydney Opera House, Sydney, Australia

This iconic structure, comprised of interlocking concrete shells, anchors one of the world’s most famous harbors. Visually stimulating and home to a menu of family-friendly performances and programs, the architectural trendsetter debuted in 1973. Whether you take in a walking tour and observe the opera house glinting in the sunlight or aglow after nightfall, you’ll appreciate its artistic vibe and global significance.

2. Angkor Wat, Cambodia

Family members who have seen the “Tomb Raider” films will particularly enjoy exploring the Angkor Archeological Park, unfolding deep within the Siem Reap province. While hundreds of archeological and artistic ancient structures remain, the most familiar (on the Cambodian flag) is Angkor Wat. Built in the 12th century to honor Hindu god Vishnu, the temple’s bas relief galleries inform visitors of life in ancient times. Also of note is the remarkable water system, including moats, canals and reservoirs. Visitors arrive via river cruises on the Mekong.

3. Amalfi Coast, Italy

Nirvana for artists, photographers and foodies, the picturesque coastal area offers a sensual mix of cultural, natural and historic wonders. While the small communities were once only accessible by mule, modern-day train travel makes it easy to visit the enchanting towns that spill toward the sea from their steep and craggy origins. During the warmer months, sailboats dot the watery landscape and boat taxis provide additional access.

4. Machu Picchu, Peru

Make your way to this extraordinary archeological site just as the Incas did. Choose from two- or four-day treks along the Inca Trail that culminate in stunning views of the “lost city” where palaces, terraces, walls and plazas cling to the mountainside. It was not until 1911, that a Peruvian guide led Yale professor Hiram Bingham to the ancient site on the eastern slopes of the Andes. Mysteries remain as to how the Incas were able to construct the complex more than 500 years ago and why it was abandoned not long after. Train trips are also available from Cusco.

5. Strasbourg, France

The French city’s old town is an island — the Grande Ile — surrounded by canals and the River Ill. Families can get a unique view of this historic enclave by paddling a canoe through the canals, including the chance to maneuver through a lock with the help of a trusted guide. You can’t miss the city’s Gothic cathedral, which rises high above Strasbourg and was said to be the world’s tallest building until 1874. Climb 320 steps to a viewing platform for a bird’s eye view. And be sure to spend time inside the cathedral, taking note of the historic stained glass windows that survived many war-torn years. Also of interest, inside the cathedral, is the world’s largest astronomical clock. Considered a Renaissance masterpiece, it was assembled by a team of artists, mathematicians and technicians, and also shows signs of the zodiac, equinoxes and leap years.
