Heritage From the Perspective of Intelligence

In the contemporary era of globalized tourism, smart tourist destinations are emerging as a necessary response to the challenges of sustainability, conservation, and quality of the visitor experience. These destinations not only integrate advanced technologies and governance strategies, but also place the preservation of natural, cultural, and architectural heritage at the center as essential pillars of their identity. Well-managed tourism can be a powerful tool for development; poorly planned, however, it can become its worst threat.

The United Nations Educational, Scientific and Cultural Organization (UNESCO) defines cultural and natural heritage as “the legacy of the past that we enjoy today and pass on to future generations.” This formulation highlights not only its exceptional value, but also its shared nature and the responsibility involved in its preservation. UNESCO maintains that these assets must have such great universal value that their loss would constitute an impoverishment for all humanity.

Within this framework, smart tourist destinations understand that heritage is not a decorative element of the landscape, but the very soul of the place. There is no tourism without narrative, and there is no narrative without history, culture, and context. Thus, the integration of natural, cultural, and architectural heritage into tourism strategies becomes a priority. 

However, when the appeal becomes excessive, new problems arise. The phenomenon of “overtourism” — excessive tourism — is a real threat to many heritage sites. Crowds damage monuments, overwhelm services, displace communities, and disrupt ecosystems. In this context, the principles of sustainability and intelligent control of tourist flows become essential. UNESCO, together with the World Tourism Organization (UNWTO), has promoted practices that include the spatial and temporal dispersion of visitors, the use of technologies to monitor influxes, and the design of inclusive policies that involve local communities as active custodians of their heritage.

Venice, declared a World Heritage Site in 1987, has for years been the symbol of the dilemmas of overwhelming tourism. Venice is not prepared to receive the millions of tourists who invade it every year. The arrival of giant cruise ships, fleeting visits by day-trippers, and the transformation of homes into tourist accommodations have blurred local life. Faced with this situation, authorities recently implemented an access fee for daily visitors and limited the size of tourist groups to 25 people. They also banned the use of loudspeakers to prevent noise pollution. While these measures aim to contain tourist pressure, UNESCO has warned that they are insufficient and has considered including Venice on the List of World Heritage in Danger. The measures, although valuable, require more coordinated governance and a more in-depth approach that considers the urban ecosystem as a whole.

As Jeremy Irons asks in “Love Letter to Venice:” What remains of the city when only visitors remain and not its inhabitants? In response to this horror vacui, the fear of emptiness, Venice implemented the above controls. These are valid but partial attempts: It will remain a city in danger if the governance of its heritage — that exceptional legacy which, as UNESCO points out, must be passed on to our descendants — is not restored.

Thousands of miles away, but with a similar problem, Machu Picchu and the city of Cuzco in Peru face challenges in managing heritage tourism. Before the pandemic, Machu Picchu received nearly 4,000 visitors per day, far exceeding the recommended levels for its conservation. In response, the maximum number of visitors was reduced to 2,244 per day and mandatory guided tours were established. Access to the sanctuary was also diversified through new, less invasive routes, and interpretation centers were built to channel part of the flow. These measures have sought to balance the need for access with the urgency of preservation, making Cuzco a positive example of how a destination can transition to a more responsible model.

A fundamental tool in this transition is the calculation of tourist-carrying capacity; that is, the scientific and technical estimate of how many people a site can receive without compromising its physical integrity, environmental balance, or cultural character. This capacity depends not only on physical space, but also on factors such as the sensitivity of the environment, the available infrastructure, and the perception of the local community. The implementation of this measure makes it possible to establish specific limits on the number of visitors per day, define time slots, anticipate cumulative impacts, and design alternative routes. 

In addition to its conservation benefits, carrying capacity can become a sustainable business model for municipalities: It allows them to charge differentiated fees, guarantee higher quality experiences, organize demand according to supply, and allocate income to maintenance, signage, specialized personnel, and educational programs. By making access a regulated and valuable experience, not only is heritage protected, but the local economy is also strengthened in a responsible manner.

The use of technology has also become key in these processes. From mobile apps that indicate tourist density in real time to smart reservation systems and sensor monitoring, smart tourist destinations are exploring solutions that combine innovation with sustainability. But technology alone is not enough. As the UN Tourism slogan “Travel – Enjoy – Respect” states, it is necessary to raise visitors' awareness of their impact and reinforce their role as respectful guests rather than demanding consumers.

For its part, governance as an integrating element of wills allows local governments, tourism companies, resident communities, organizations, and visitors to discuss and build consensus on how to preserve the soul of places. Because while tourism can bring income, it can also take away what is most valuable: authenticity, memory, balance.

Cities such as London and Paris have embraced the intelligent management of their heritage with hybrid approaches. Museums and historic sites now offer high-resolution virtual tours, augmented reality in iconic spaces, and digital experiences that allow visitors to inhabit the city without setting foot in it. This reduces pressure on crowded areas, such as Montmartre, the London Eye, Notre Dame, or the Royal Palaces, and democratizes cultural access. In addition, strategies such as staggered schedules, online reservations, alternative routes, and apps to distribute tourists to less frequented neighborhoods help preserve their architectural heritage without sacrificing the experience.

These examples share a common logic: defining carrying capacity as a limit, charging for access as an investment, involving smart technologies, and making heritage a partner with a purpose, from agave and landscape to Venetian canals, recent drone tours of Stonehenge, or virtual tours of the Louvre. In each case, communicating that heritage is not a finite asset but a living legacy that must flow over time, allowing visitors to become conscious custodians rather than superficial consumers.

And so, smart tourism becomes synonymous with respect: respect for the generations who saw the birth of a city, a culture, and for those who, in the future, will continue to tell and live those stories.
