Today, we want to talk about some iconic places where Cooperating Volunteers has projects, so you can visit them during your free time as part of your volunteer experience. While you can find articles about many of them on our blog, where we discuss their history and unique features, today we’ll focus on the number of visitors these iconic monuments receive in various cities.
- MACHU PICCHU / PERU
Machu Picchu is one of the most iconic and visited archaeological sites in the world, located in the Cusco region of Peru. Built in the 15th century by the Inca civilization, this citadel is renowned for its impressive stone architecture, perfectly integrated with the mountainous Andes landscape.
In 1983, UNESCO declared Machu Picchu a World Heritage Site, and in 2007, it was selected as one of the New Seven Wonders of the World.
Visitors can reach Machu Picchu by train from Cusco or by hiking the famous Inca Trail, an experience that combines nature and history.
This site receives more than 1.5 million tourists annually, making it one of the most popular tourist destinations in Latin America and the world. However, due to concerns about site preservation and environmental impact, measures have been implemented to limit daily visitors.
Currently, around 4,044 people are allowed entry per day, divided into staggered time slots. Tourists must purchase tickets in advance, as access is regulated to prevent structural deterioration and protect the region’s flora and fauna. In many cases, an official guide is required to ensure visitors follow designated routes and respect site rules.
These restrictions aim to preserve the integrity of this archaeological treasure for future generations while allowing visitors to enjoy an unforgettable experience.
Visiting Machu Picchu is truly unforgettable.
- CHICHÉN ITZÁ / MEXICO
Chichén Itzá is one of the most important archaeological sites in Mexico and an iconic city of the ancient Maya civilization. Located on the Yucatán Peninsula, this impressive complex blends architecture, astronomy, and art in a place full of mysticism. In 1988, UNESCO declared it a World Heritage Site, and in 2007, it was recognized as one of the New Seven Wonders of the World.
Chichén Itzá is one of the most visited sites in Mexico, attracting over 2 million tourists annually due to its historical significance, easy access from Cancún and Mérida, and the unique experience it offers visitors.
Chichén Itzá symbolizes the ingenuity and sophistication of the ancient Maya in architecture, mathematics, astronomy, and urban planning. Its conservation and promotion are essential to preserving Mexico’s rich cultural heritage.
Since 2006, tourists have not been allowed to climb the Kukulkán pyramid or other structures to prevent wear and tear. Access to certain areas has been restricted to minimize human impact, and inspections are conducted regularly to address damage caused by erosion, weather, or time. Restoration efforts use techniques that respect original methods and materials.
Although no strict limits on visitor numbers have been imposed (as seen in Machu Picchu), authorities regulate tourist flow through set hours and entry fees. Trained guides educate visitors on the site’s importance and ensure rules are followed.
- THE ACROPOLIS / GREECE
The Acropolis of Athens is one of the most iconic monuments of ancient Greece and a symbol of cultural, political, and artistic development during the Hellenic civilization. Situated on a rocky hill in the heart of Athens, this citadel features some of the most important architectural works of classical antiquity, primarily built in the 5th century BC during the height of Athenian democracy.
Over the centuries, the Acropolis has faced challenges, including wars, looting, earthquakes, and modern pollution. Nevertheless, extensive restoration and conservation efforts have been implemented.
Restoration projects, initiated in the 19th century and ongoing, focus on repairing damage from neglect, conflict, and misuse. Advanced techniques are used to restore structures, employing marble from the original quarry when needed. Measures such as traffic reduction in the area and periodic cleaning with lasers have been taken to combat air pollution and acid rain damage.
Recognized as a UNESCO World Heritage Site, the Acropolis attracts millions of visitors annually—about 3 million—but during the summer, up to 20,000 visitors per day are permitted, a limit imposed in 2023 by Greek authorities.
- TAJ MAHAL / INDIA
The Taj Mahal, located in Agra, India, is one of the world’s most iconic architectural masterpieces and a symbol of eternal love. Built between 1631 and 1648 by Mughal Emperor Shah Jahan in memory of his favorite wife, Mumtaz Mahal, this white marble mausoleum represents a fusion of Islamic, Persian, Ottoman, and Indian styles.
The Taj Mahal has faced challenges over the years, including pollution, erosion, and mass tourism.
Preservation measures include restricting polluting vehicles near the site, periodic restoration with cleaning treatments like Fuller’s Earth to remove stains and restore the marble’s shine, reforestation projects in the surrounding area, and limiting daily visitors to a maximum of 40,000. Different entry fees apply for domestic and international tourists.
This monument, a UNESCO World Heritage Site since 1983 and one of the New Seven Wonders of the World in 2007, attracts over 6 million visitors annually, making it one of the most visited destinations in India and globally.
- CHRIST THE REDEEMER / BRAZIL
Christ the Redeemer is one of the world’s most iconic statues and a symbol of Rio de Janeiro, Brazil. This colossal monument, representing Jesus Christ with open arms as a gesture of welcome and peace, is situated atop Mount Corcovado within the Tijuca National Park.
Located 710 meters above sea level, it offers panoramic views of Rio de Janeiro, including iconic sites like Copacabana and Ipanema beaches, Sugarloaf Mountain, and Maracanã Stadium.
Preservation involves regular maintenance to repair damage caused by erosion, tropical weather, and lightning strikes. A major restoration in 2010 included cleaning the outer surface and applying new layers of soapstone. Since the statue is within Tijuca National Park, both the statue and its natural surroundings are protected.
Receiving over 2 million visitors annually, Christ the Redeemer is one of Brazil’s top attractions. In 2012, it was declared a UNESCO World Heritage Site, and in 2007, it was named one of the New Seven Wonders of the World.
